Dear Foamer,

During the parallel run of any OpenFOAM solver (pimpleFoam in my case), each processor has its own sub-mesh (stored in case/porcessorX/constant), which is a part of the global mesh. Moreover, each processor has no idea about the sub-meshes stored in the other processor.

How can I get the list of the cellCenter or the faceCenter of each sub-meshes? For example, I tried with mesh().C(), but the output size is the same for all sub-meshes, which is not possible (the scotch decomposition never gives sub-meshes with *exactly* the same size...). Here is a piece of code I added after the line #include "createMesh.H":
Code:
#include "createMesh.H"

Pout << "nb of cell center in processor"<< Pstream::myProcNo() << " = " << mesh.C().size() << endl;
And the output is the following (parallel run on 2 cpus):
Code:
[1] nb of cell center in processor1 = 1011456
[0] nb of cell center in processor0 = 1011456
Any ideas?

Cheers,
Marcel
