opening parallel cas and dat files

darp · August 22, 2011, 14:34

Hello all,
I've got a bother with Fluent 12.0: I set up my transient case in parallel on 4 processors, run some time steps and then complate the run on an 8 node cluster.
When I try to open the last cas and dat I get an error message
"%non-conformal-mesh?: invalid grid
(..\src\mpsystem.c@1148): mpt_read: failed: errno = 10054
: mpt_read: error: read failed trying to read 8 bytes: No error"

Reading the last TS dat on my initial cas gives me (although nothing has been changed):
Warning: case and data files are inconsistent; zone 27, case [1747482,1776023], data [1747182,1775723]

Trying to open them in serial does not help either.

What am I doing wrong? Has anyone come across these errors before? Any suggestions?
Thanks
Darp

Was your previous cas&dat file saved correctly? If not, such errors might happen.
