I think I found the problem regarding the mesh refinement issue in parallel mode. Probably, it is not even related to the boundary indicators. From what I understood, there is a problem with the MPI_Allreduce function I mentioned in the previous post: https://groups.google.com/forum/#!topic/dealii/aDEP1MSS0JA. Hence, Daniel was totally right. I cite:
- *n_vertices() only gives you the number of vertices for one process, not > the global one.* In particular, you can't rely on the fact that this is > the same for all processes. Furthermore, you (probably) don't initialize > all the values of your struct. This might be the reason for the large > numbers you are observing. > I observed that my total number of nodes (* triangulation.n_vertices() *) and elements ( *triangulation.n_active_cells()* ) remain the same even after refinement, but the total number of degrees of freedom ( *dof_handler.n_dofs()* ) are updated. Is there a possibility to obtain the total number of nodes after refinement/coarsening or do I have to use the DoF information somehow? Sorry for the confusion.
