Hi this is Mithun, I am relatively new to OF. I am trying to do a snappyHex mesh in parallel. In order to do so I follow this sequence.
blockMesh
decomposePar
foamJob -s -p renumberMesh -overwrite
foamJob -s -p snappyHexMesh -overwrite

The error that I receive is as follows
I would appreciate if someone can help me in layman's terms.

mpirun has exited due to process rank 2 with PID 3228 on
node PFSNSQ855105 exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Yup, I found this post because I'm getting the same error. And worse is that I'm reconstructing a simulation from a case setup that I did last year, and it meshed just fine. The difference is that I've upgraded OpenFOAM to 3.0 since then, but I'm not sure how that would effect snappyHexMesh.

Perhaps its time to downgrade OpenFOAM and give it another try, but I still wish I knew what this error meant.
