Default parallel processor

I am trying to resolve my model with a computer with processors in parallel. My geometry is a boiler so that is not an easy geometry but not totally tricky as well. I am trying first to use only 2 processors in parallel and i got this error message: ////////////////////////// iter continuity x-velocity y-velocity z-velocity energy k epsilon do-intensi time/iter unable to read the cmd header on the pmi context, generic socket failure, error stack: MPIDU_Sock_wait(2533): The specified network name is no longer available. (errno 64).

999999 (..\..\src\mpsystem.c@1123): mpt_read: failed: errno = 10054

999999: mpt_read: error: read failed trying to read 4 bytes: No such file or directory unable to read the cmd header on the pmi context, generic socket failure, error stack: MPIDU_Sock_wait(2533): The specified network name is no longer available. (errno 64).

job aborted: rank: node: exit code[: error message] 0: fluent.int-aet.dk: 123 1: fluent.int-aet.dk: -1073741819: process 1 exited without calling finalize The Parallel FLUENT process could not be started. ///////////////////////////

I was thinking first that i could not have a partition trough the porous zone of my heat exchanger but even without crossing the heat exchanger zone it doesnt work. I am using a metis partition ( i tried as well with others ) which seems the best in my case but without positive results. I would be pleased if you can help me Thank you

Try to read the msh with the 1core version. Set the case. Then read it in parallel. Let us know.

it is actually working with autopartition. I dont really know why cos the metis partition looks better. If anyone has an idea , thank you
