Parallel partitioning of a matrix to solve by e.g. GAMG
 

Hi,

I want to use an own solver instead of GAMG or the other ones OpenFOAM has included. In serial this already works pretty fine, but unfortunatly I have not been able to figure out how the matrix is decomposed in a parallel run, yet, although I've been gone though a lot of OpenFOAM code until now.
Does anyone have any idea about where OpenFOAM might perform this or perhaps how the partition vector defining this is named ?

It would be very kind of you if anyone could help me.

Thanks,

Sebi
