Dear Jean-Paul, > Yes, this looks like a copy-paste error in the documentation. Would you > like to submit a patch to correct it? >
Sure. How and where can I submit a patch? When you refine cells at a boundary, the child cell's faces will inherit > the boundary and manifold ID's of the parent cells regardless of whether > the mesh was read in or created using the GridGenerator functions. > But according to the documentation this is only true for sequential triangulations and not for distributed triangulations. It is more safe to update boundary IDs while the distributed::parallel::Triangulation::execute_coarsening_and_refinement function is running. I cite: This is not necessary for sequential triangulations because, there, these flags are inherited from mother to child cell and remain with a cell even if it is refined and the children are later coarsened again, but this does not hold for distributed triangulations. See: https://www.dealii.org/developer/doxygen/deal.II/classparallel_1_1distributed_1_1Triangulation.html There is a slight problem using the approach written there. I am trying to compile the following: triangulation.signals.post_refinement.connect(std_cxx11::bind(& SolidMechanics<dim>::set_boundary_ids, std_cxx11::cref(*this), std_cxx11:: ref(triangulation))); Then I receive the following compilation error: /usr/include/c++/5/functional(1426): error: static assertion failed with "Wrong number of arguments for pointer-to-member" static_assert(_Varargs::value ^ detected during: instantiation of class "std::_Bind_check_arity<_Tp _Class::*, _BoundArgs...> [with _Tp=void (), _Class=SolidMechanics<2>, _BoundArgs=<std::reference_wrapper<const SolidMechanics<2>>, std::reference_wrapper<dealii::parallel::distributed::Triangulation<2, 2>>>]" at line 1440 instantiation of class "std::_Bind_helper<_SocketLike, _Func, _BoundArgs...> [with _SocketLike=false, _Func=void (SolidMechanics<2>::*)(), _BoundArgs=<std::reference_wrapper<const SolidMechanics<2>>, std::reference_wrapper<dealii::parallel::distributed::Triangulation<2, 2>>>]" at line 787 of "/home/seyedali/fe_models/deal.II/solid_mechanics/solid_mechanics.cc" instantiation of "void SolidMechanics<dim>::create_geometry() [with dim=2]" at line 544 of "/home/seyedali/fe_models/deal.II/solid_mechanics/solid_mechanics.cc" instantiation of "void SolidMechanics<dim>::do_initial_timestep() [with dim=2]" at line 1440 of "/home/seyedali/fe_models/deal.II/solid_mechanics/solid_mechanics.cc" instantiation of "void SolidMechanics<dim>::run() [with dim=2]" at line 1472 of "/home/seyedali/fe_models/deal.II/solid_mechanics/solid_mechanics.cc" /home/seyedali/programming/c++/libraries/boost-1.62.0/include/boost/function/function_template.hpp(159): error: no instance of overloaded function "std::_Bind<_Functor (_Bound_args...)>::operator() [with _Functor=std::_Mem_fn<void (SolidMechanics<2>::*)()>, _Bound_args=<std::reference_wrapper<const SolidMechanics<2>>, std::reference_wrapper<dealii::parallel::distributed::Triangulation<2, 2>>>]" matches the argument list object type is: std::_Bind<std::_Mem_fn<void (SolidMechanics<2>::*)()> (std::reference_wrapper<const SolidMechanics<2>>, std::reference_wrapper<dealii::parallel::distributed::Triangulation<2, 2>>)> BOOST_FUNCTION_RETURN((*f)(BOOST_FUNCTION_ARGS));
