Hi!

I have problem with running my dynamic mesh case in parallel. Basically sonicFoam works fine for me in both parallel and serial, but sonicDyMFoam only works in serial. It crashes with a floating point exception. I'm running OF version 2.1.0 on Ubuntu. I have tried different decomposition methods (simple, scotch) and different number of partitions. I have also tried the preservePatches option when decomposing since my case contains cyclic patches but without success. It also appears to crash at the same step.

Below is a typical log of a crashing run.

Does anyone have any idea what causes this? Any help is welcome.

/ Johan
