DMP solver crash

MFiX Bug report

BUG REPORT

Type of issue
solver crash

Description
Details on how to reproduce the issue. If MFiX crashed or failed, how long does it take? I built the DMP solver in GUI. Built was successful. But when a simulation is lauched, the solver crashes immediately, but proceeds with calculations

Attempts to fix the issue
Rebuilding the solver

I see that your solver has both SMP and DMP enabled. While this should be OK, I think it might be the source of the problem (since the crash is in a function marked _omp_fn). Try disabling SMP and rebuilding the solver.

Rebuilding with DMP only did not help
