Dear community, I have a problem in the assembly part when solving Step-74 (DG method) by MPI. Generally speaking, we can first determine whether one cell is locally owned or not by cell->is_locally_owned(), and then assemble matrices and residuals by hands (e.g. Step-40 for CG and “Distributed LDG Method” for DG in code gallery). However, Step-74 using Meshworker and FEInterfaceValues classes automatically loops and assembles all cells, faces, and interfaces. My question is how to identify one cell which is locally owned or not in Step-74. Is there any deal.II code combining discontinuous Galerkin method (which uses FEInterfaceValues class, e.g. Step-12 and Step-74) with MPI (either PETSc or Trilinos)? Any help is going to be appreciated.
