error in the beginning of parallel porocessing
 

when I run the Fluent I see this message:

Updating mesh at time level N... MPI Application rank 2 exited before MPI_Finalize() with status -1073741819
The fl process could not be started

what is meaning of this message?

Looks like an MPI problem. Can you describe your setup a little more? Is this a new issue or never before seen? Basically, a Fluent process did not start on one of the parallel nodes as expected. Did your nodes even boot up properly before that?

Have you tried tinkering with your MPI? Is this on a compute cluster or a workstation/desktop?
