multiphaseEulerFoam running in serial but crashing in parallel

BlnPhoenix · January 20, 2017, 11:38

I'm running a three phase simulation with multiphaseEulerfoam. The case runs in serial but crashes in parallel using the "scotch" decomposition method. A should also mention that i use a MRF for rotation in my domain.

What can cause the crash in parallel? I'm confident that BC etc. are correct since they do just fine in serial.

For there may be someone in the future with similar problems. Check whether you recently changed your RAM. I doubled my RAM but had to use the smaller voltage of the two. This instabilty made OpenFoam crash in parallel i supose.
