Parallel run diverges, serial does not

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 |

Hi Samuel,
there are a few threads about similar issues. Try to have a look to these two, for example: http://www.cfd-online.com/Forums/ope...tml#post215615 http://www.cfd-online.com/Forums/ope...llel-runs.html Hope this helps, Francesco |
