May 8, 2009, 10:50	Parallel run diverges, serial does not	#1
SammyB New Member Samuel Braun Join Date: Mar 2009 Posts: 1 Rep Power: 0	Hi, 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. Samuel
