Hi all,

I would like to run finite area solvers in parallel.

I copied both liquidFilmFoam and surfactantFoam tutorials, adding in the system folder the decomposeParDict from incompressible/simpleFoam/pitzDaily tutorial.

After blockMesh and makeFaMesh, I've decompose the case using decomposePar without a hitch.

Finally, I've tried to run the case in parallel typing "runParallel surfactantFoam 4 &", getting this error:

--------------------------------------------------------------------------

MPI_ABORT was invoked on rank 2 in communicator MPI_COMM_WORLD 

with errorcode 1.



NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.

You may or may not see output from other processes, depending on

exactly when Open MPI kills them.

--------------------------------------------------------------------------

I get the same error with all the finite-area-method tutorials. I haven't found any suggestion for this.

Is the above procedure correct?

I'm not able to figure out where this error came from .



Thanks,



Andrea

This afternoon I've tried the same tutorials in parallel using foam-extend-3.2 and all successfully run.
Therefore, I guess it is an issue related to foam-extend-4.0.
