yes, regardless of how you do XFEM now (manually with FESystem and FE_Nothing or via FE_Enriched), you would need to use hp::DoFHandler. > So, then this would, at present, not work with p::d::triangulation. correct, see https://github.com/dealii/dealii/issues/3511 <https://github.com/dealii/dealii/issues/3511> note that you can still use MPI for linear algebra, matrices and vectors, but you would need to store the whole triangulation on each core. > Would the general point be that if one can go to higher resolutions with > distributed parallelism that the enhanced accuracy of the enrichment > functions can be compensated for? Sorry, i did not get what you mean.
