Dear deal.II developers,
I have a question regarding fully distributed Triangulations. I start with a *Triangulation<dim> *on each rank, and partition it using *TriangulationDescription::Utilities::create_description_from_triangulation()* to construct a *parallel::fullydistributed::Triangulation<dim>* across multiple MPI ranks. On the serial Triangulation, I compute some data associated with vertex DoFs (i.e., for a Q1 or P1 element, one DoF per vertex), using full mesh information. I would now like to transfer this data to the fully distributed Triangulation. However, I’ve found that the global indices of the same vertices differ between the serial and distributed meshes. I have tried matching vertices using their Point<dim> coordinates, but I would prefer a more robust or built-in solution if available. Is there a recommended way to obtain or construct a mapping between the vertex (or DoF) indices in the serial Triangulation and those in the fully distributed Triangulation? Any suggestions would be greatly appreciated.
