Hi colleagues, I have a question for parallel::distributed::Triangulation When 2 cells share 1 edge, but they are living in 2 different MPI processes, how can I choose only 1 cell containing the common edge from them. I think I have to set material id for the cell in the first process, and then tell the other one do not set it. However, I don't know how to send the cell iterator in MPI communication.
Could you please help me to address this issue? Thank you very much.
