The issue occurs when you install OpenFoam per instructions.  The instructions for the SU2 Solver direct you to install MPI V10.  Apparently it's assumed that OpenFoam contains MPI V10 but you really need to install it from the Microsoft website.  This resolves the error.

Thank you for confirming the issue, and that installing MPI V10 separately helps. It is not quite clear yet why a separate MPI install is necessary, as OpenFOAM typically comes with its own, the OpenFOAM instructions will be updated once this is clear.
