Detailed Description
CombinedSystem and combineSystems for composing independent physics into a coupled system.
Individual physics sub-systems (SolidMechanicsSystem, ThermalSystem, ...) remain authoritative for their own configuration APIs. combineSystems wires them together via a shared FieldStore and provides a coupled setMaterial that registers integrands on both sub-system weak forms.
Usage:
auto field_store = std::make_shared<FieldStore>(mesh, 100, "coupled");
auto solid_fields = registerSolidMechanicsFields<dim, disp_order, DispRule>(field_store);
auto thermal_fields = registerThermalFields<dim, temp_order, TempRule>(field_store);
auto solid_system = buildSolidMechanicsSystem<dim, disp_order, DispRule>(
solid_solver, solid_opts, solid_fields, couplingFields(thermal_fields), param_fields);
auto thermal_system = buildThermalSystem<dim, temp_order, TempRule>(
thermal_solver, thermal_opts, thermal_fields, couplingFields(solid_fields));
auto coupled = combineSystems(solid, thermal);
coupled->setMaterial(thermo_mech_material, domain); // tight coupling
solid->addTraction(right, traction_fn); // loose via sub-system
thermal->addHeatFlux(top, flux_fn);
auto advancer = makeAdvancer(coupled);
auto combineSystems(std::shared_ptr< SubSystems >... subs)
Combine two or more independently-built sub-systems into a CombinedSystem.
