Hi! I had made a parallel simulation in a 2CPU compute.When fluent read the case (.cas) in auto partition ,there were such errors :

Parallel variables... Building...

grid,

auto partitioning mesh by Principal Y-Coordinate,

distributing mesh

parts..,

faces.., 999999 (..\..\src\mpsystem.c@1228): mpt_read: failed: errno = 10054

999999: mpt_read: error: read failed trying to read 4 bytes: Invalid argument

Process [0] exited with status [-1073741819] Process [1] exited with status [259] MPIRUN exited with status [126] The Parallel FLUENT process could not be started.

Why so? And how to deal with?

I also had such problem. What I understood is, it is due to the insufficient memory. I obserbed that when i did partitioning for the same case with 2 CPUs but with higher allocated memory, everything was ok. Also, i tried with reduced number of cells in the domain, on the machine with relatively low memory, again everything was fine. So probably, memory problem in your case.
