Thanks, Jean-Paul. I was thinking maybe something in the same way like step-40.
I tried your approach, but can I just set it equal to each other? I did the following: *Main class* LA::MPI::Vector configurational_forces; LA::MPI::Vector local_configurational_forces; *setup_system() class* configurational_forces.reinit(locally_owned_dofs, locally_relevant_dofs, mpi_com); *compute_config_forces() class* Vector<double> cell_cf(dofs_per_cell); // Cell Configurational forces typename DoFHandler<dim>::active_cell_iterator cell = dof_handler.begin_active(), endc = dof_handler.end(); for (; cell != endc; ++cell) { if ( cell->is_locally_owned() ) { fe_values.reinit(cell); cell_cf = 0; ... // Configurational force computation ... ... cell->get_dof_indices(local_dof_indices); constraints.distribute_local_to_global(cell_cf, local_dof_indices, *local_configurational_forces*); } } *local_configurational_forces*.compress(VectorOperation::add); *output_results() class* // ========================[ CONFIGURATIONAL FORCES ]========================== configurational_forces = local_configurational_forces; *(here I receive an error!)* std::vector<std::string> configurational_forces_magnitude(dim, "config_forces"); std::vector<DataComponentInterpretation::DataComponentInterpretation> configurational_forces_interpretation(dim, DataComponentInterpretation::component_is_part_of_vector); data_out.add_data_vector(configurational_forces, configurational_forces_magnitude, DataOut<dim>::type_dof_data, configurational_forces_interpretation); I receive the following error: make all Scanning dependencies of target solid_mechanics [ 50%] Building CXX object CMakeFiles/solid_mechanics.dir/solid_mechanics.cc.o /home/seyedali/fe_models/deal.II/solid_mechanics/solid_mechanics.cc(950): error: no operator "=" matches these operands operand types are: const dealii::LinearAlgebraPETSc::MPI::Vector = const dealii::LinearAlgebraPETSc::MPI::Vector configurational_forces = local_configurational_forces; ^ detected during: instantiation of "void SolidMechanics<dim>::do_initial_timestep() [with dim=2]" at line 1081 instantiation of "void SolidMechanics<dim>::run() [with dim=2]" at line 1113 compilation aborted for /home/seyedali/fe_models/deal.II/solid_mechanics/solid_mechanics.cc (code 2) make[2]: *** [CMakeFiles/solid_mechanics.dir/solid_mechanics.cc.o] Fehler 2 CMakeFiles/solid_mechanics.dir/build.make:62: die Regel für Ziel „CMakeFiles/solid_mechanics.dir/solid_mechanics.cc.o“ scheiterte CMakeFiles/Makefile2:195: die Regel für Ziel „CMakeFiles/solid_mechanics.dir/all“ scheiterte make[1]: *** [CMakeFiles/solid_mechanics.dir/all] Fehler 2 Makefile:83: die Regel für Ziel „all“ scheiterte make: *** [all] Fehler 2 I assume the size doesn't match. Can I really just write it like you suggested? Kind regards, S. A.
