Hi Denis, Thank you for the pointer! This is very helpful. The below is my understanding (and please let me know if I am wrong): 1. If we do the L2 projection over a domain of elements, then it smooths the stress jumps in the sense of integration. The stress would be continuous over the domain

Dear Mathieu, As Maxi already pointed out, step-33 is indeed not written to take advantage of any MPI capabilities. Perhaps somewhat unintuitively the call to Utilities::MPI::MPI_InitFinalize mpi_initialization(argc, argv, ::numbers::invalid_unsigned_int); in the main() function configures th
