Hello!

This is a short and hopefully simple question: We have invested some time to understand the underlying data format of OpenFOAM as we need to write a custom solver. For single processor runs, this was not too difficult.

Could someone give me a pointer to the documentation for the parallel data structures? Are they documented somewhere?

Best regards,
Henrik

Parallel cases are just like n
 

Parallel cases are just like non-parallel cases. They additionally have a few patches (procBoundaryXXX) and corresponding patch fields ('processor') to communicate to neighbouring processors.

all standard operations (fvc::, fvm:http://www.cfd-online.com/OpenFOAM_D...part/happy.gif on fields (volXXXField, surfaceXXXField) are parallel aware.
