Dear Foamers,
It seems that the preservePatches option of the decomposePar utility actually means that for all faces of a preserved patch have the owner and neighbor on the same processor (as commented in code)? What if I want to preserve a complete patch (or two identical patches) in one processor using the scotch method, is it doable? I can do it with the simple method but I thought there maybe a lazier way to do it and to somehow preserve processor weights? ![]() Best regards Hisham |

Dear Hisham,
I'm also trying to get a certain patch preserved. PreservePatches doesn't seem to work right now so I'm looking forward to the result of your 'experiment'. Did you also try to use manual instead of scotch? Regards, Ralph

Greetings to both!
There was a bug report on this that hasn't been closed yet: http://www.openfoam.org/mantisbt/view.php?id=387 Best regards, Bruno

Dear Bruno, thanks for your reply.
I tried to test this option yesterday (OF2.1) but unfortunately I don't have cyclic patches so this option doesn't seem to work for me or am I wrong? Would there be another way to preserve non-cyclic patches? Maybe a manual decomposition? Ralph

Hi Ralph,
I don't have much time to go into details, so here is the summary:
