Results showing NaN's when Acusolve run on multiple processors

Hi Everyone,

I am trying to get Acusolve working on my university's HPC, and I have a simple internal flow test case that I am using. When I solve the problem with one processor, multiple threads, it gives the expected results, but when I run with multiple processors -- even on the same node of the HPC -- the results show up as NaN values. The solver did not give any error during execution (none that I can see in the *.Log file).

Results from a run with 1 processor ^^^^^

Results from run with multiple processors (MPI) ^^^^^^

Do any of you know why this could be happening?

I am loading the results into Altair SimLab to view them. Could this just be an issue with the way SimLab is reading the results?

Thanks,

Josh
