Hi Adam,
From the transcript that you sent, it looks like your path has a space in it. I advise you to get rid of that space. (*Probably* not an issue here, but it will be if you start using UDFs.) Other thoughts: -- Try "standard" initialization instead. -- Check that you are not missing any input files (flamelet models, inlet profiles, viewfactors, or whatever). -- Go through all the settings and check that there are no blank entries. -- Go through all the monitor definitions and check that they are valid. Maybe, as a paranoid measure, delete all the monitor plots, all the monitor files and all the report definitions (in that order). -- You could try the "Check Case" button. -- If none of this works, try a simpler case (maybe a tutorial), to troubleshoot whether the problem is with that case or the whole installation. Good luck! Ed |

This is some parallel/mpi error. In fluent 19 there is no longer a serial mode so don't expect it to fix anything. Try using a different mpi, you are using ibm mpi.
