Utilities::MPI::all_gather(comm, locally_owned_dofs()) upon the first invocation, including global communication. Use Utilities::MPI::all_gather(comm, dof_handler.locally_owned_dofs()) instead if using up to a few thousands of MPI ranks or some variant involving local communication with more processors. Utilities::MPI::all_gather(comm, locally_owned_dofs_mg()) upon the first invocation, including global communication. Use Utilities::MPI::all_gather(comm, dof_handler.locally_owned_dofs_mg()) instead if using up to a few thousands of MPI ranks or some variant involving local communication with more processors. Utilities::MPI::all_gather(comm, n_locally_owned_dofs() upon the first invocation, including global communication. Use Utilities::MPI::all_gather(comm, dof_handler.n_locally_owned_dofs() instead if using up to a few thousands of MPI ranks or some variant involving local communication with more processors. const second argument. const second argument. selected_dofs has to have a length equal to all global degrees of freedom. Consequently, this does not scale to very large problems, and this is also why the function is deprecated. If you need the functionality of this function for parallel triangulations, then you need to use the other DoFTools::extract_boundary_dofs() function that returns its information via an IndexSet object. ShortPRM instead of ShortText. PRM instead of Text. do_reinit is deprecated: please use the overload with a sparsity pattern argument instead. do_reinit is deprecated: please use the overload with a sparsity pattern argument instead. reinit is deprecated: please use the overload with a sparsity pattern argument instead. reinit is deprecated: please use the overload with a sparsity pattern argument instead. solve_with_jacobian callback described below. unsigned int and a const ReferenceCell & instead.
