Dear All, I was just wondering in a MPI run, is there a critical number of finite-elements to be present in the base mesh on each processor when doing an adaptive refinement of the base mesh using p4est in deal ii. I had a base uniform mesh of 64 elements and when I try to do adaptive refinement using triangulation.execute_coarsening_and_refinement(), the code gets stuck at this function call when I run more than 8 processors. However, if the base mesh has 512 elements, the code gets stuck at the same function call when I run on 16 processors.
