I am trying to querry for the jump in my solution with "get_jump_in_function_values" . My solution vector is PETSc distributed. When I run a code that's like the one below:
template <int dim> void output_jumps<dim>::interface_jump() { QGauss<dim - 1> face_quadrature_formula(degree + 1); FEInterfaceValues<dim> fe_iv(fe, face_quadrature_formula, UpdateFlags(update_values | update_gradients | update_quadrature_points | update_normal_vectors | update_JxW_values)); const unsigned int n_face_q_points = face_quadrature_formula.size(); std::vector<Tensor<2, dim>> gradu(n_face_q_points); typename DoFHandler<dim>::active_cell_iterator cell = dof_handler. begin_active(), endc = dof_handler.end(); const FEValuesExtractors::Vector displacements(0); for (; cell != endc; ++cell) if (cell->is_locally_owned()) for (unsigned int face = 0; face < GeometryInfo<dim>::faces_per_cell; ++face ) if (cell->face(face)->user_flag_set()) { // I want to visit the face only once cell->face(face)->clear_user_flag(); auto cellnb = cell->neighbor(face); int nface_number = cell->neighbor_face_no(face); fe_iv.reinit(cell, face, numbers::invalid_unsigned_int, cellnb, nface_number, numbers::invalid_unsigned_int); // This line breaks running code in parallel fe_iv[displacements].get_jump_in_function_values(current_solution, jumpu); } } I get the error: "You tried to access element 512 of a distributed vector, but only elements in range [0,511] are stored locally and can be accessed." How can I access the ghost entries to calculate the jump in my solution? -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
