refineMesh -parallel crashes (in cavity tutorial)
 
Dear foamers,
I am trying to use refineMesh in parallel on the 'cavity' tutorial, running

$ mpirun -np num_procs refineMesh -parallel

after decomposing the case using the scotch method. checkMesh crashes and gives following MPI error:

----
[host:PID] *** An error occurred in MPI_Recv
[host:PID] *** on communicator MPI_COMM_WORLD
[host:PID] *** MPI_ERR_TRUNCATE: message truncated
[host:PID] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort)
----

checkMesh -parallel and refineMesh (single) work just fine. This error occurs in OF-1.6 and OF-1.6.x. Needless to say it is the same with with more complicated meshes...

Is this a case of PEBCAK ?


Cheers,
Andras
