Hello Foamers,

could anybody please explain how to communicate across a processorPolyPatch? For reading (ghost) information belonging to another processor I use

const scalarField myGhostInformation (myVolScalarField.boundaryField())[myPatch].patchNeighbourField();

and it works fine. But I wonder how to change this ghost information belonging to another processor.

I guess I need some MPI staff, I went through a lot of files like OPstream.H, UPstream.H etc but I have not found any peer-peer communication tools.

(Usually I do not need this while computing fluids but these days I am working on particles moving through the domain (lagrangian approach) and I need to communicate between processors peer to peer)

Thanks a lot in advance,

Honza
