I could get this example ran fine. However, it gave error when I changed the ‘ REAC fuel’. The original fuel used in the example (couch.fds) is propane, and actually the fuel I used is also propane but just the syntax to insert in the fds text file is different.\r\n\r\nI used the propane description from the FDS6; page 143-144 to replace the single REAC line of the original file.  When I ran the case, an error (as below) ‘on the element N’ turned up.\r\n\r\nERROR: Problem with REAC   1.
