    Solver abnormal termination error - not a memory issue?

      Hi,

       

      I was hoping someone here could help me figure out how this error is happening. I am running an analysis of flow around an object (travelling very fast) and am receiving the "abnormally detected" error above at iteration #25. I know for sure that this is not a memory issue, first because I have a good deal of RAM on this computer, and second because the log says that the memory is OK.

       

      If it helps at all, for the first few iterations I receive an error about a high mach number (I have checked the "high mach number" option). That goes away after a while, so I assumed it is just due to the error-reducing process of iteration.

       

      Here is what I assume the relevant part of the log.

       

       

      Iteration   25

      I tried to open r_abnorm.fld in a Notepad file, but it is gibberish. Any suggestions?

       

      This is my first attempt at the SW Flow Simulation, so it is not outside the realm of reason that I am doing something very wrong in setting up this simulation. If someone has any suspicions about what I am doing wrong, I would be glad to provide any relevant settings to help diagnose the problem.

       

      Thank you very much in advance
