Hi Berk, thanks for your answer. I think I'm missing something.... you said cells only?!
If I understood this subject correctly, a cell should be considered ghost if it's held by more than one partition/process, isn't it?! In this case, there'll be an overlapped layer of elements. The problem is that my MPI solver does not make use of this overlapped layer of cells/elements. It only has nodes/points that are shared by processes. This explains why I asked by a ghost node (shared node would be more appropriated to define such kind of node). Can I consider a cell as ghost if it touches the parallel interface (without overlapping)? Would it work? Regards Renato.
