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. Yours sincerely, Kien Vào Th 4, 27 thg

Dear community, this looks a simple question but I just cannot find a simple answer, I apologize. The code I aim at writing is similar to: *unsigned* vv = 0 ; *for* (*unsigned* *int* ii=0; ii this_node = cell->vertex(vv) ; [ ... omitted

[deal.II] Re: Can dealii handle different type of element in a grid

Hi, deal.II only supports quads in 2D and hex in 3D.So if you have triangles you will need to split them. For the quads, you probably want to load order one quads and then, use a manifold to get the higher order. step 49 (https://dealii.org/current/doxygen/deal.II/step_49.html) shows how to
