Parallel run diverges, serial does not
I have a case which runs fine in parallel with OpenMpi and serial without turbulence model. Unfortunately, the parallel run with turbulence model on (e.g. kE->LaunderGibsonRSTM) segfaults after few iterations.
Whereas the serial run seems to converge (still running).

Could this be a problem of the used preconditioner (p: GAMG, others: DILU)?
Could someone, please, point me to a possible solution?

Thanks and have a nice weekend.
