In order for MOOSE and OpenFOAM to share an MPI world within Hippo, we needed to patch OpenFOAM to prevent it from calling MPI_Init itself and enable us to pass through a pointer to an already initialised MPI communicator.
This will pose a bit of a maintenance headache in the future and makes it hard to upgrade OpenFOAM and even install Hippo.
We need a plan for how to deal with this in the future. Long term, getting a version of the patch merged upstream is probably the best option.
