I put this up to give anyone a first idea of the new structure, see the actual diff to current master, and also to ask for an opinion on the following:\r\nThe current particle implementation is completely based on the tracers postprocessor, which only outputs their properties. I was asked by @EGP-CIG-REU for additional postprocessors who do stuff with tracers, and afaik Scott wants to implement some more active properties. Therefore, I would argue that the tracers in their new form should live in their own world as a part of simulator instead of a part of this particular postprocessor. This would make things easier for all plugins who would like to query something from the particles (e.g. particle count per cell etc.), and it also would be more consistent with the current directory structure. To make this consistently however, it would probably require changes to the Parameter file structure that would be incompatible. On the other hand, it would only affect models, which used tracers, and I think that are not many (because the particles were more or less useless so far).\r\n@bangerth, would you agree with that?\r\n\r\nThere is still a list of things that I want to do before merging including:\r\n- a generator based on a probability density function\r\n- a generator in which particles get generated according to the positions in an ascii file\r\n- a system to query properties with certain names from particles (instead of just all properties)\r\n- the RK2MultiStep Integrator is not yet finished\r\n- cleanup + speed optimization"},"comment":{"url":"https://api.github.com/repos/geodynamics/aspect/issues/comments/127941293","html_url":"https://github.com/geodynamics/aspect/pull/411#issuecomment-127941293","issue_url":"https://api.github.com/repos/geodynamics/aspect/issues/411","id":127941293,"user":{"login":"gassmoeller","id":7582930,"avatar_url":"https://avatars.githubusercontent.com/u/7582930?v=3","gravatar_id":"","url":"https://api.github.com/users/gassmoeller","html_url":"https://github.com/gassmoeller","followers_url":"https://api.github.com/users/gassmoeller/followers","following_url":"https://api.github.com/users/gassmoeller/following{/other_user}","gists_url":"https://api.github.com/users/gassmoeller/gists{/gist_id}","starred_url":"https://api.github.com/users/gassmoeller/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gassmoeller/subscriptions","organizations_url":"https://api.github.com/users/gassmoeller/orgs","repos_url":"https://api.github.com/users/gassmoeller/repos","events_url":"https://api.github.com/users/gassmoeller/events{/privacy}","received_events_url":"https://api.github.com/users/gassmoeller/received_events","type":"User","site_admin":false},"created_at":"2015-08-05T09:51:47Z","updated_at":"2015-08-05T09:51:47Z","body":"It was me (Rene).
