Tourism and health officials are rolling out a thorough plan for the management of the Atlantic Rally for Cruisers once participants arrive at the IGI Rodney B. Marina in early December. Hermadi Mark breaks down the processes in place. Strict protocols are being announced by the St Lucia Tourism Authority and the events company of St Lucia, guided by the Ministry of Health for the Atlantic Rally for Cruisers, ARC. Plans to manage the arrival, testing and screening process were outlined at a media walkthrough at the Vence venue, the IGI Rodney B. Marina. Participants were mandated to arrive in Las Palmas no less than one week prior to the scheduled departure. They went through mandatory PCR testing and remained in isolation until living Las Palmas. Participants were also briefed on St Lucia's strict protocols and information on each participant will be handed to the Ministry of Health prior to their arrival in St Lucia. Valon Shamor is an environmental health officer with the Port Health Department of the Ministry of Health and Wellness. Upon entry to St Lucia, persons are screened by the Port Health team. The nurses will do the necessary checks and ensure that persons are COVID-free basically. If the information presented to the Ministry of Health shows any anomalies, the vessel in question will be asked to remain on anchor on the bay and the issue will be addressed there. The average ARC participant will spend an average of 21 days in isolation on their way to St Lucia. The general manager for the IGI Rodney B. Marina, Chandevo, explains the protocols for vessels in the racing class. We have designated a dock which we'll walk around to show you which is J-Dock and that dock is the quarantine dock. So for example for a vessel that is going to arrive in 12 days, the balance of their quarantine must be done at the dock where they will not be allowed to get off the boat, they will not be allowed to walk down the dock or anything else. Provisions have been put in place by the sponsors and the tenants of the marina to make deliveries to the vessel but again those deliveries are done at a distance where the items are placed on the deck of the boat and those on board and the delivery supplier are distanced more than 40 feet apart because it's the length of the boat. When on quarantine those clients will be placed with a red band by the port health for the duration of their quarantine period. Participants will be given blue bands at the end of the process to indicate that they have completed their final quarantine period from the Government Information Service, Hermione Mark reporting.

pleasure and now Roma wines of Fresno, California that's R-O-M-A Roma wines bring you suspense tonight from New York Roma wines present Miss Eva Legalian distinguished star of the New York stage in phobia a suspense play produced edited and directed for Shanley by William Spear suspense radio's outstanding theater thrills is brought to you by Roma R-O-M-A Roma wines the greatest name in wine there's nothing like the tantalizing aroma of juicy steak sizzling on the barbecue or the taste of spicy cold cuts and crispy cooled salad served outdoors and to make warm with the dishes more tempting serve tall frosty glasses of Roma wine and soda yes Roma wine and soda is ideal with some of meals or anytime friends drop in simply half filled glasses with your favorite Roma California wine robust Roma burgundy or fragrance or turn filled with ice and soda garnish and sweetened to taste cry refreshing Roma wine and soda it's inexpensive and always better tasting with Roma America's favorite wine now Roma wines bring you Eva Legalian in a remarkable tale of suspense yes I'm the Emily Haven whose pictures you saw in the papers you can tell of course by the wheelchair I thought it was very unkind of them to take full-length pictures it isn't that I resent the wheelchair but people have funny ideas about such things the way they wrote about me being a sweet little lady you'd have thought I was at least a hundred and a helpless invalid well I can tell you right now I'm neither I'm not supposed to have any excitement but goodness knows we've had enough of that around here with the murder and all you probably wonder why with all our money I don't have one of those new type modern chairs it's just that I can't stand the feel of metal no no metal it affects me like snakes or spiders do some people I've always been that way when I was a child mother let me use knives and forks with bone handles and I still use them I'm certainly glad that the papers didn't find out about that or about grace they almost found out about great grace once and printed large headlines police question wealthy woman you probably don't remember it because they never did learn why she was questioned that was some time ago grace had just returned from shopping in here Grace did you bring my book yes here you are and I brought another one I thought you'd like I'm tired sit down we'll have Anna bring some tea let's have a look at your loot what do you mean by that by the things you bought of course I guess I'm so tired I'm jumpy come to gentlemen to see you mom oh bring some hot tea please Anna do you like something to eat grace not till dinner just tea then Anna and show the gentlemen in yes mom why don't we let her go and get someone who doesn't answer yes mom to everything no we couldn't replace Anna she knows us too well why do you say that you are jumpy only meant that she knows our likes and dislikes and humors us I suppose you're right but I don't like the way she watches oh that's just Anna's way she doesn't mean anything by Haven yes I am Henry Lane I'm a assistant store manager at Bradlocks oh yes Mr. Lane one of our store detectives observed your sisters are unusual actions today and reported them to Sergeant Cole oh pardon me this is Sergeant Cole how do you do I didn't want to turn it until I talked to Lane here yes yes Sergeant Cole wisely came to me and we are here to rectify the error I'm afraid I don't follow you Mr. Lane I'm sure there's a satisfactory explanation to your sister's behavior we'll get to the point but he's trying to say is that I took some things from the store without paying for them grace that's what was reported to me you admit that you took these things I just admitted it why grace impulse I guess but you have plenty of money I know I think that's what starts the impulse you mean you've had the impulse before that an official or a social question don't be flippant I'm not the whole thing is a farce we've always gotten everything we want by signing a check and we'll continue to do so you think if I were anyone else we'd be sitting here like this Miss Haven no I'd be sitting in jail waiting to be lost I've taken things before and probably will again mostly I don't even want the things the thrill of taking them you've said enough grace are you going to arrest me now sergeant arrest you I grace grace will you see if Anna's made tea and bring two extra cups and a checked book grace I'm sorry this comes as a shock to me it's anything I ever believe me I regret having to trouble you've been very considerate I I'm sure we can rectify the entire matter if you care to estimate the amount sounds like a bribe no not at all let us say a retribution I don't know I feel that it's only right that you should receive something for your time and regard sergeant no lady I I don't want to press charges and in the future Mr. Lane if you will assign someone to watch my sister when she's shopping in your store you may send the bill for the unpaid items to me yes there may be a slight fee oh yes yes I understand now if you'll hand me my pen checkbook thank you there you are I think I hear Anna coming with the tea was a dreary tea there were little frosted cakes sergeant cold rock crumbs all over the rug and mr. Lane said between noisy sips grace him to enjoy it though she sat and watched one and then the other she has an unusual sense of humor that was the way mr. Lane started coming to our house I don't know how it happened but eventually we were calling him Henry he was pleasant enough and I think we might have been friends if he hadn't learned about me too entirely by accident he'd been bringing up presents from the store and although I suspected that he'd gotten them in the same manner that Grace did it was a nice thoughtful thing to do one night when he came he was feeling playful how are the two lovely ladies tonight oh very well thank you Henry isn't he gallant tonight it isn't difficult to be gallant with you now put your heels together and kiss our great what to see what I brought for you yes uncle you have such a charming way of jesting yes we do have our little jokes don't tease Henry show us what you brought you should be surprised first how nice and I will put it on you now turn around with you back to me now don't look there a necklace a silver necklace just what I want very attractive on you Grace thank you Henry and now for Emily no don't ask me to turn my back no no no just hold out your hand close your eyes and hold out your hand that seems so childish Henry play the game oh very well are you ready there metal I can't stand the feel of metal I do think my phobia saved my life as you know we have a large amount of silver in the house and although I have an aversion to touching it I like to see it around Grace is always bringing home some peace reminds me I wonder if she you excuse me a moment I I think I'll just have to lie down for a moment Roma wine presentation tonight in radio's outstanding theater of thrills suspense Roma wines those better tasting California wines that add so much to the daily joy of good living there's a reason why Roma wines are so much better tasting the better taste of Roma begins with the lush goodness of choice California grapes tenderly pressed and guided unhurriedly with the ancient skill of Roma master Vintners and America's greatest winemaking resources then these

phobia a tale well calculated to keep you in Grace was out for the evening and Anna had gone to bed I was sitting here in my chair reading suddenly I thought I heard someone moving in the hall I called out but no one answered so I thought it was my imagination and then I heard it again I sat very still listening and watching the hall door as I watched the nods began to turn someone was slowly pulling the door Anna Anna is that you answer me for you why do you have your face covered I will not keep quiet what you have in that case I said keep quiet silver that's our silver I want no trouble you you put that silver back or you'll have trouble I'll film the police I'll call for help this is your own don't point that gun at me you can't scare me with that I haven't long to live anywhere you ain't gonna have long to live you don't stop that gap and stay where you are do you hear me stay away I'll look here sister I ain't kidding now you look here you ought to be ashamed the great big man with a gun robbing a helpless lady in a wheelchair I want besides that you're very rude take your hat off in the house hey what is this if you want to come into my house you learn some manners and then knock on the door now set that silver down leave the room looks like I'm gonna have to tie something don't touch me don't touch by having her wash all the silliest when he came it seems that he wanted to check for fingerprints he was mollified however when he found fingerprints on the silver cabinet I hadn't thought of that so Anna had to wash that too Sergeant Cole came back to tell us that the fingerprints belonged to a man by the name of Mr. Scorchy Hood he was wanted by the police because you'd escaped from some penitentiary and was what Sergeant Cole called a killer Mr. Hood was called Scorchy because he always shot people from close range and usually in the neck Sergeant Cole thought it was very amusing when I said if he was going to kill me he would have to stand back I wouldn't have him touch me with that gun did you read those uncouth headlines in the papers wealthy woman match for murderer haven defeats hood they made me sound like a pugilist the papers are so unkind people's money one morning Anna came into the room without knocking so I said Anna I didn't bring I've got to talk to you mom very well Anna what is it it's about my broach the one my mother gave me what about your broach it's gone mom you mean you lost it no I didn't lose it it was in my room and now it's gone well you probably mislaid it no no I didn't mom I always keep it pinned to my Sunday dress and it's not fair I don't see how I can help you I thought maybe you'd like to replace it oh what kind of pin was it it was a cannibal but this time I thought I'd I'd like to have one with some diamonds and little pearls I don't understand I've been cleaning this grace's room and she's got a lot of strange stuff there that nobody knows how she come by she's even got a gun you've been snooping and I'm just cleaning mom I did kind of look for my broach I see do you want your pen miss Emily oh yes and me my pen thank you there you are you think that will replace the brooch oh yes thank you well hey day in the middle of the month yes I mean no just a little token miss great token of what let's call it pin money that will be all Anna thank you mom now mom you tell me what this is all about it's nothing grace really when you sign a check it can't be classified as nothing it was a pin for Anna that isn't very funny Emily pin money for a pin what about a pin she lost it lost it oh I see now let's not talk about it anymore grace but I want to talk about it for dear anyone can get money from you can't grace please I may have my impulses I've never taken anything from the servants yet grace where are you going what are you going to do deliver you just purchased a pin and I'm going to find it and wear so impulsive she's always been good to me she brings me nice surprises sometimes I get a bill for them and when I don't I enjoy them even more Grace is really very serious minded and she worries about trifles like leaving me alone with Henry Henry never was dull always full of new ideas I've never told her he proposed to me came in a complete surprise Emily I need more money I gave you a check last week Henry for your relief funds isn't very clear in my mind what relief fund that was for let us matter now the point is that I need a great deal more money for this time for me Emily oh Henry you disappoint me so much more fun when you try to fool me I'm tired of that I think I'd like to marry into the family that's out of the question I'm sure Grace would never consider it great who else good heavens you you don't mean yes you ever now why would you want to marry a woman in a wheelchair you just gave the reason you haven't long to live Emily after you're gone was your husband I didn't had a great I think you'd better go Henry go until I've had my answer what kind of proposal is that will you and your money marry me oh no you have to do better than that perhaps I can Henry what are you doing with that candlestick I'm going to persuade you oh you can beat me to death I won't change my mind you misunderstand Emily I'm not going to beat you I'm going to caress you Henry you wouldn't your arm your throat your back no I don't want to talk I want to keep away don't touch me keep away I don't like to excite you like this it isn't good for you how how soon do you want to be married Henry immediately how about tomorrow so soon when you make up your mind to do something why wait suppose you're right oh I would like some tea Henry would you shall I ring for Anna well she's asleep by now why don't you get it yes leave it to me just leave everything to me I was annoyed at Henry for his crassness was very tiresome I'm gonna be so cruel I've wheeled my chair about the room I have a habit of doing that when I'm disturbed presently I heard Henry returning with the team door opened a little there was that deafening explosion of a gun the doors to motionless for a moment and slam shut I was too stunned I just sat looked I tried once to open it but it wouldn't budge I was still sitting there when the police came wasn't Sergeant Cole was a new man called Inspector Wells I think there was a man with him but I'm a little confused about that night Henry had been shot was lying against the door that was why the door wouldn't open the gun was on the floor beside him the inspector asked a lot of questions and everyone talked at once I'll tell you like I told him after the shot I don't remember hearing footsteps or the door outside close it may have happened but I was too excited to remember Anna tried to make the inspector believe that Grace had killed Henry she told him about the gun Anna has spells of being difficult I think it's because of the pin she doesn't like Grace to wear it it took Henry away and we went to bed the hall was a mess we had to have the carpet clean and there are still some tea stains on the wall the next morning I made a discovery that I thought would interest the inspector so I phoned him he came right up come in inspector you say you find a brooch in the hall yes this one under a chair inspector you know who belongs to our maid Anna I need a fancy for a maid isn't it diamonds and small pearls Emily bought it for her that's quite a gift we like to keep our help satisfied I'd like to talk to her our caller who killed Henry inspector don't know yet we're having the gun check fingerprints that all the police do check fingerprints you ring mom yes and I come in inspector wants to ask you some questions yes mom did you see Henry Lane last night you mean while he was alive yes did you see him before he was shot only for a minute when was that I heard a noise in the kitchen and I looked in to see who it was that was when he went for the tea trust Anna to look in did you speak to him maybe a few words did you like Mr. Lane like him I did not he was no gentleman why do you say that he used to say unkind things to me is this your pin why yes where'd you get it was found under a chair in the hall it couldn't have been I didn't have it on last night you mean you weren't wearing it when you shot him shot him oh my goodness you don't think I shot him right now we suspect everyone I didn't kill him honest I didn't oh please tell him I didn't mom you tell him oh inspector it's just occurred to me I've made a horrible mistake I remember now that I saw Anna wearing that pin when she served breakfast this morning so she couldn't have dropped it last night oh thank you mom thank you I don't think the inspector was convinced when he left he didn't say he wasn't he looked was kind of a kid but it was worth it Anna has been an angel ever since she cleans graces room and never sees a thing she even returned some things that grace didn't know were missing I gave Anna the pin and she put it back on her Sunday dress the inspector phoned around noon he was very excited he said the blurred fingerprints on the gun belong to mr. scotch he would and that we should be very careful and he hadn't been caught and he was dangerous I asked him how we should go about being careful he said to lock the doors and windows and they would send a man to watch the house I didn't think we needed to worry somehow I couldn't believe mr. scotchy hood wanted to hear me scream again but about 10 o'clock Grace and I were sitting here discussing Humphrey Bogart when the whole hall door open I've no intention of moving what do you want shut up sister don't call me sister my name is Emily and this is my sister grace how do you do this ain't no social call I'm glad to see you've uncovered your face I don't know why you should cover it it really isn't unpleasant face at all I won't do you no good did you come to kill us you guessed it sister grace grace hey what are you doing of me trying to confuse me why should you want to kill us mr. hood because you made people laugh at me the papers made fun of me I can't stand up what seems to me you brought it on yourself you came uninvited in the first place what kind of talk is that sure I didn't I come the same way this time if you're going to kill me you'll have to stand away from me you see I have a phobia what a phobia it's something I can't help why don't you stand over there why on account of my phobia it'd be better if you stood there no no a little father yes I think that's better oh grace sir will you straighten the rug I'll call the man across the street oh grace look what you've done when he hit his head on the table he spilled the flowers now that water will make white spots on the barnish how mr. hood was wanted for several murders so they executed him I'm rather sorry it's all over seems dull around here now and I did so want to enjoy my last days the doctor says I've only six months at the most I haven't told Grace my time is so short would cause her to fret grace worries that's why I didn't tell her that I took the gun and shot Henry as he opened the door and then toss the gun into the hall before he slumped against the door and pushed it shut I hadn't even told her that mr.

So, let's go ahead and go to the home directory here everything we have already in the source file. So, now the first thing is let's have a location for you to save your no solvers. So, for that let's create a directory. We have that one project this is this will take you to the source location of your user line folder. These are directly you want to go. And in there let's say I create folder of applications and solvers. Please make sure you don't do any mistake in line I mean in the spelling of this because later on then I get new test issue. So, what I have done is just created one new folder in my run directory. In my user directory I created this new folder applications solvers. And WM project source user directory is taking you to this location. Then anyone can say done yes. So, now that we have copied the solvers. So, let's copy our we are going to modify the icofoam solver. So, it's like incompressible solver and based on ISO piece of algorithm. And we are going to incorporate temperature equations in it. Okay, so you and P will be solved by piece of algorithm icofoam and we will add a new temperature equation. So, we will obviously take our maybe a stock solver piece of solver and then modify it to add the temperature equation. So, for that I am going to copy my from foam solvers foam solvers. I will copy incompressible icofoam copy it where we are going to copy it to our new solver location. That is WM project user directory applications solvers and let's say I rename my new solver as my foam. Any issue till here, copying this file done till here. So, let's go to this new location where our solvers are my foam. So, I will go inside my my foam and let's check what are the files inside this. So, this is very basic solver just the nearest of solver which has found the main directory create fields and icofoam see. So, the first step we will do is this replace this C file because our new solver will be my foam. So, I will move my icofoam C to my foam C.  I mean, difficult to, I mean you will replace the icofoam previous which has come with 54. So, for that my foam C I will replace it. So, now let's go to the make folder. This is the I think previous tutorial also you have got some idea when you have do the turbulence modeling tutorial. So, let's actually we need to edit it right. So, the first thing we need to add it is in the make folder where you are setting the locations of your new files. So, here I will mine you for C file is my foam and executable will be in the user bin. And then we have this our folder is also named as my foam. So, please make sure you make these changes to files done someone. So, okay, so let's take it once again. So, we have we have not modified anything yet. So, let's do wmech so that we know that our new solver is ready. If I do wmech it will compile this new solver depending on your system it will take some time. So, it compiled without any error make sure you are on the same page. I am clearing my screen give me a thumbs up or something so that I know people are following. Don't clear. Okay, don't clear. This you don't need this is automatic. I mean why you are worried. Okay, someone don't want to clear. Okay, carry on. Not bad. So, let's say inside this there is another pile and we are not going to modify anything but let us just see that folder. So, later on when you will have let's say you want to couple your say all area and some of us. So, there the time you may need to change your options. So, here you are actually you just see the create fields and one C file. But actually it is this options. We are actually locating all the files that are present in the source folder of finite volume include and mess tools on all the libraries in the finite volume and mesh tools. So, later on let's say you want to incorporate a turbulence model you need to source the turbulence thing you need to say Lagrangian multiple model. If you see those solvers you will see few more lines and you can you can estimate that how you are going to modify your own solvers whether you need to incorporate new things or some things. So, this is very basic thing we just need to add equation. So, we don't need to add anything else. I'm closing it. Okay. So, we have done that turbulence thing. So, now we can add it in the create fields. In this file what are the things I need to add? Can anyone tell me? I need to add a temperature equation. Come on. Not bad. So, I need to add a temperature equation. So, it will have a material property that is thermal diffusivity. So, for that I need to and here you can see the open form in this file. It reads the files so input output dictionary that is transfer property. In the transfer property it is actually reading already a user defined function which are defined value of dynamic viscosity. So, similarly I will add a thermal. So, I will just copy this and paste it here and let's say I rename this new variable as dt. And in the transfer property it will be read with the term dt. Dimensions are same as dimension of viscosity. So, I don't need to change in there. Here also look up for the term dt. These changes if you have made and you have incorporated and we have added the variable thermal diffusivity. So, this is an input output dictionary how you read take values from user one way to take define a variable. Now, let's say there is another way to define the variable. Density we don't we are solving incomprehensible. So, we don't need to worry about density here and it is not a dynamic viscosity. It is already a kinetic viscosity. So, let's say the other variable that has independent variable that we have already pressure and velocity. So, you can see the one is a scalar value and one other is a vector value. But you can see the syntax. Syntax is remain same. Just in the first line you need to define volume scalar value and vector value. Another is this the size and all in which variable in which mess you are defining the variable. These things are taken care over here. And then you have some options over here input output objects. This is needed whether to read the boundary condition and whether when you want to get the output. So, the first thing is if it is must read then it means that it will ask for a boundary condition. The other option is no read then it will it won't ask for the boundary conditions. And you auto write or no write. If you don't want to get save that as an output you can keep it as no write. And otherwise keep it as auto write. It will automatically present on your control field dictionary what to define in your control parameters it will write. So, what we are going to do is we are going to copy this because temperature is a scalar value. Let me copy it from the presser to the size. Okay. I am replacing the P with P. Yes. People followed. I am going to close it. So, we have added some new variables. One was independent variable T and one is like user defined variable that is DT. So, after that we I will go to map add actually and change what then add the equation in the my form. So, where I need to add this temperature equation. So, if you see here I mean before this this is the main file main solver run directly. So, this is the main function and before this it's like you set the initial conditions. You set the calculate the initial continuity error, create mesh, create time. So, set up your control parameters and set up your root cache file so that you can do the post processing things. And from this line your time loop starts. Can somebody tell me where should I add this temperature equation? Outside the time loop, where should I add my temperature equation? Here I have controlling the current number from that I am calculating the delta T. We are setting the new equation solving the new equation and this is the PISO algorithm. So, I will maybe in the slides I will discuss with all this PISO algorithm works. So, once you get the pressure and you equation. So, we are solving temperature as a specific scale. So, I don't need to be incorporated in that like PISO algorithm. After the PISO algorithm when I will get my UNB field I will add the temperature equation inside the time loop. So, that it solves at every time. So, what I am going to do is I am going to copy this every scale of function here. Paste it over there. But I need to modify this in this. So, it is everything at SMP. Something you can do famously and add before. So, FBN, DT. It is the DT term for temperature. And the MPM divergence term for temperature. The volume plus 5 temperature T. And that question. So, that question should be between the people followed. And then I will begin this equation as T equation. And I am going to solve this equation. I will give some time here people to add this term. Then I will save this. Krishna, can you repeat that my form is hitting once again? So, like the description of the solver that I said something. Yeah, I mean the editing that you did. Someone lost it. Editing only? Yeah. Editing. So, after this PISO loop I am getting my velocity and pressure field. So, and I want to solve my temperature equation inside the time loop. So, before this run time and after getting the velocity that this PISO loop is ending in this passage. So, after that I have added this temperature equation here. You can see. This is the non-orthogonal loop. And before that it is the PISO correction loop that is ending over here. So, after that I am writing the temperature equation. There is no source term in this temperature equation for simplicity. So, in this I am solving the temperature without the coupling. So, if you want to do the coupling then I think you need to add a source term in your U equation. Here you will come with a function of t. And also if you have added something here then you need to take care of that in here also in getting the fluxes here. So, that modification also you need to do. And then you will have a coupled velocity and temperature function. Solver. So, if okay then I will close this file. Good. So, I have added these things. So, I have done the modification in my solver. So, let's do the loop and compile it once again. So, let's see. There is no error. I am hitting the problem. I am clearing it. So, from here now that I have made my new solver I need to define a new case file. Hello, Mr. Krishnan. Yes. I am getting an error. What error? Erase, permission denied. Okay. So, then you might have the app user being there. You need to modify it. So, the main folder, the files. Here you need to make it own user app. Make sure you are too distant. Can you please zoom it a bit? I mean I am not going to. Yeah. Okay. One second just. Thank you. Good. So, let's go to the run directory to make a case file for this new solver. So, now I am in the run directory. So, I will again copy my cavity case and modify in there. So, I will copy it from point to point. And let's say I copy it to my cavity. So, let's set it. My cavity is there. So, let's go into the my cavity. So, what are the things that I need to do here? Can somebody tell me? So, first of all, I have defined a user defined function that is DT. So, I need to define it somewhere, right? But let's see. That is in the constant property file. Constant transfer properties. I need to define DT term here. And the dimensions are going to be same as me. So, I am taking that previously. And let's say previously, in the previous case, I have followed it. So, I keep it 2e minus 3. But let's say, I mean, in the previous case, I have not make those changes. So, for me, I will do this 4e minus 5. That was previously when I run the cases 4e minus 5. Okay. So, and then I need to change this to DT. Okay. You people followed at this line? Yes. So, I think you people did this, right? So, what are the changes again I need to do? Can somebody comment? I have defined a new equation. T file, yes. Other than that, we will do that later. Other than that, I have defined a new equation. So, for this new equation to solve, I need to define the boundary conditions. Okay. I need to define the schemes and solver also. So, to do that, I will go and take my schemes. So, what I need is, I have defined a divergence term for temperature. So, for that, I need to copy this. I have this IT term in my equation. So, for that, it is this. And let's say my divergence scheme for temperature will be okay. So, after this Laplacian scheme, I don't need to, I mean, I can define separately Laplacian DTT. But by default, it is Gaussian and orthogonal. And for all the Laplacian's command, it will take that orthogonal. And that is what I want. So, I don't need to add the Laplacian scheme here for temperature. So, let me close this file if you guys have done till here. Yes, no. So, after this, I need to define a solver also for this solution. So, the new equation, the algebraic equation that will be created, I need to define a solver for that. So, for that, I will copy this new whole command, do this here. So, the T equation will be you solve this set of commands, smooth solver, a smoother. Let us replace it with Gauss-Seidel. Okay, rest of the things say as it is, I think I need to define the final. So, I will do that. If not required also, it won't harm also. So, the final is defined. This changes if you have done. Then I will close this. I have defined a solver for temperature equation. In notepad typo, so open form, I mean notepad won't know what you want to type. So, the typo error type and all those things, I mean once you will be like getting used to it, use it frequently, those things won't happen. So, don't worry about that. So, I am saving this. So, now boundary conditions that you just told me, I need to define that. I go inside the zero directory. And here I have this U and P file. So, I will copy this P file to a T file. So, that I don't need to create P file again. So, just a little modification I need to do now. P file, not required. So, what are the changes I need to do? This looks easy. P should be T. After that, dimensions. Temperature equation. And it is like the previously that without source term that we have done the case. So, let me keep the boundary conditions same as that. So, I will define it as 300. I will define this as its value. So, I will keep some time here. If people have done, I am okay. Everybody following? Yes, sir. So, I will control it and I have not done any modification, not required. So, I will run the case now. My phone. Because the new solver is named as my phone. So, to run this new solver, the new command will be my phone. So, okay, the time question and time also is different. So, maybe we won't be able to compare it. But still, so, you can see that we have this solved for the, you know, solved for the temperature equation. So, like that, we will do this. Check it in the paraform. So, like this, you may just touch my phone. Especially like this in temperature. So, I think I made a mistake somewhere. The temperature of I should not come like this. Can anyone guess where is the mistake? I think I should change the solver itself. You don't need to repeat it. The process is done. So, let us see if I do this change what will be the result.  So, I just made the modification of Laplacian term that is negative to positive. So, those changes, let's see what will be the result. Did it other result? It is overwriting. So, now you got the procedure right for how to modify it in all temperature. Adding equation, user defined variable and adding equation. So, maybe I need to like check once again what is the equation and all. But this is the overall procedure. Let me just go in order. So, the previous term was on the right anyway. So, you have created the solver. Let me show you some of the links of the quotes. Someone is asking me why didn't you change the control dict? My application in control dict. My application because I am running directly through the command. You need not to change it, right? You need not to change it. If you want to run it through the shell files that you create, all run script files, then in that you use underscore get application. So, if you want to use the script file, then you need to read that application. There you need it. So, I have some glimpse of other quotes that you may, I mean you may find it anywhere in the CFP of your domain and all, but it will help you to accelerate. So, how you can do your coding like the first thing you need to a cell loop. So, in here you can see how a cell loop is written in your code, how a face loop is written in your code, and how you can loop over the cells and the faces inside it. So, that is the code. So, you will have the video. So, you don't need to save it or anything. This is how you do it. Already in the previous tutorial, people have defined how you can use a different function but I also included it. But let's say you have some mathematical functions inside your boundary equation then to include those functions, then you need to make, then you may use this snippet of code. So, this is a sample of that. Any questions you can ask? So, let's say another function that I want to write is to, let's say I want to get an output function. I want to get output of, let's say, kinetic energy of the system and also I want to get the dissipation energy of the system. So, in here you can see that the first line is actually when you have parallel processing then you use this to get the total number of cells from counting all the processes. So, the total number of cells will do the summation of the velocity vector field in parallel and you get an average reward. So, some examples only the motivator just show you some examples of how you can proceed and how you can do these things. So, that is my motivator. So, to show you, you can define just inside a volume new scalar field where just inside the code itself, you're going to slip through also in the volume of the scalar field and you can use the U component X component to define the new variable U X, U Y and then you need to know that once you copy, once you get a gradient of a scalar field then it becomes a vector field. So, to say that you need to define the volume vector field, similarly to get the magnitude of the vector becomes a scalar. So, some steps are that I am showing you here and a cell loop to calculate the kinetic energy of all the cells and the dissipation energy of all the cells. And this is a two phase flow. So, it is a problem with the volume fraction alpha and one-one cell flow. So, and then I have to save that first. So, let's say if kinetic energy to, I have already in the cell here, I have already defined the pointer for kinetic energy. So, this is the snapshot of how you can get the output in a file with the file name, let's say KDAT. Just inside the time loop if you can keep it at each time step, you can get something. So, this is not big thing. It is small itself. It may accelerate your work other than this. I need out if you people are having, then you can ask. I can show some more quotes. Let's say sometimes you need, when you define the equation dimensions, open form was with dimensions. Sometimes in your equations, you may need to change, add a dummy variable, which will change the dimension of your equations. So, let me show you how you can do that. So, here I have my solver. This is middle form. I will show you in the create fields. So, let's say here I have this, how you can define dummy variables. So, let's say beam change in this color. So, this will be of dimension length. Otherwise, you can in the bracket inside, you can define all the fundamental dimension and define a new variable with even dimension. So, once you, how you will modify it, let's say on your equation. So, here you can see that I am adding the dummy variable because my level, this is the equation for levels such as colorful or multi-phase flow. So, for that, I am adding this, because the gradient, it is delta T, the grid function, it is multiplying with the grid function, but the variable is non-dimensional variable. So, I need to divide it so that the gradient and the multi-designed will lead up to a non-dimensional variable. So, this is one way. I mean, very frequently, actually you need to do distance. As you develop the solvers. That is a given name for my solver. That is, I am just showing you, it's not mean for you to do it. That is my customized solver, you won't find it. So, if anything you may ask, or I will ask. So, then we, I can show you how to define, what is your algorithm? Now that I have time, then I will describe it. So, in the equation that you see in the, the first equation, the first thing that you see is the u matrix was solved. So, in that, it is defining the matrix without the pressure term, which will lead up to a matrix form of this. And very frequently you will see terms h by a and all in all the incompressible solver at this, which is, h is here is the residual part, which is the source term of the equation, minus the non-diagonal terms of the, from the matrix of the u, which is defined as the h. And h by a will be the diagonal term of u, when divided by h, h by a is there. So, to solve the u equation, when you solve it, you add the source term and you get a predicted velocity field, which will be solving this h by u minus a diagonal term of u. Okay. So, and then in incompressible flow, I think you all might be aware, like we have this continuity equation, which converts to the pressure and equation for pressure. And it comes from this equation, but when you do the integration of this continuity equation, then you control volume, it changes to a divergence here. And the sf.uf, where then the predicted velocity field, if you keep that uf, which will be interpreted from the velocity field, calculated previously. So, if you do that, and then you will get the Laplacian equation for pressure, which will be solved in the p equation. If someone has doubt, they can ask, if someone is asking you, can you explain the part where you edited the minefoam.c file to add the t equation? Okay. So, let's go to the location.  And here I am defining the u equation that I said without pressure term, it is defined over here. And then we have, we solve the equation with the adding pressure as a system. And then first of all, I get the ap, like that is the diagonal term of the u equation matrix that is stored in here. And then this is the h by a term. And then we calculate from this vector field, it is just a velocity field. And then we calculate it as flux, pi by a and u on the temperature. So, after further solving of the non-absorbent part, non-absorbent loop, and the piece of loop is ending here. So, I am adding temperature equation here. So, that it is inside the time loop, but after getting the velocity and pressure field, I can start. Yeah, this is it. Here, we are making somebody sometime ask, like, why, what is the error that it is representing continuity? So, this is a file where we calculate the continuity error. And it should be less than power minus 8 or as less as possible. So, your system is stable. Any more question in this? What is this FBB flux is doing? Can somebody tell me? So, the flux is nothing but u dot s of vector. So, that is what it is doing. And once we get the flux, again, we have this term here. And that is for, like, say, because you are interpreting the points velocity field to the phase velocity field. So, the interpolation has some errors. So, to reduce that error, we have this additional term. At this file, constant pressure, these are two of the various boundary conditions to remain stable and consistent. So, we need this term, this one here, that you remember sometimes, like in the fluent, we define the external pressure field. So, that is what also is defined in open form. Also, that line is over here, equation set reference. For the given reference cell, you define the reference value. Flux is calculated after the pressure correction step and the velocity level. So, I am closing it. You can even have any question. Then I am here. You have to search it. You can spend some time. Actually, you people are doing great for the TDA workshop, but to get the glimpse of all the solvers, you need to spend some time and read some tutorials, some files. Like, Chandan Boussar has shared some links, right? You can go through the links. Other platforms are here, the online, and then open form, it has its own user guide. So, you can go through that and then you will get the idea of solvers that you want to. You can put your instruction manual to write our own solver. I think Chalmers' website is a very good starting point for the basics to start your own development part. So, you can go through that website. They are giving a lot of tutorial on how you can merge one solver with another. And of course, I think it will be a strange problem that you have the solidification part. So, I think most of you have the question like which solver to use and to get the idea of which solver you need to work on. So, actually you can just in the open form website there is a description of all the solvers, basic solvers, what it does, and from that you will come to know. The actual answer to this will come with experience and related to your topic experience. It will be a plus if you have the better understanding of C++ but to do like basic amount of coding like depending the user different condition and some sort of report you can start doing it and once you start doing it you will automatically learn. So, start doing it and you are good to start and basically with little knowledge you are able to start. Reference regarding solver beach solver, I mean there are a lot of references for a lot of solvers. User open form user guide will be a good starting point for all of you. Okay, I will share that link. Yeah. I think which actually this gives the description of all the solvers I will share once this presentation my session on this. So, I hope there are no more questions so we can take a tea break of 15 minutes. So, please come back by 3.40 then 3.45 we will start with Mr. Divesh Bariya's session.
