Accessing MPI protocols in solver
 

I am looking at running an OpenFOAM solver in parallel through a scheduling program that we have been working on. This would require passing in a new MPI communicator to the solver being called. I have not found any documentation or examples showing how to directly edit the MPI comm for a solver. Is there a way to access it?

Thanks

You could start by taking a look at the mpi wrappers that foam uses, the Pstream functions.

They are found here:
