Re: [deal.II] make hanging node constraint for locally refined mesh
Dear Prof. Wolfgang Bangerth, I used FE_NedelecSZ element. Thus, the conforming FE_Nedelec and FE_NedelecSZ can only work with the conforming mesh. The non-conforming mesh, which has hanging nodes, does not work with these elements. Thank you very much.

[deal.II] make hanging node constraint for locally refined mesh
Dear all,
When I try to create a locally refined mesh by the following codes:
* GridGenerator::hyper_cube(triangulation, 0, 1);Point
center (0.5, 0.5, 0.5);triangulation.refine_global(5);
for (auto cell : triangulation.active_cell_iterators()) {
if (cell->is_locally_owned()) {if
(cell->point_inside(center)){
cell->set_refine_flag();}}
}triangulation.execute_coarsening_and_refinement();*
The library return this error
* const dealii::FullMatrix& dealii::FiniteElement<,
>::constraints(const dealii::internal::SubfaceCase&) const
[with int dim = 3; int spacedim = 3]The violated condition was:
(this->dofs_per_face == 0) || (interface_constraints.m() != 0)Additional
information: The finite element for which you try to obtain hanging
node constraints does not appear to implement them.*
Does this error comes from the AffineConstraints when I try to implement
the DoFTools::make_hanging_node_constraints?
Could you please help me to overcome this error?
Thank you very much.
Best regards,
Kien
