Re: [deal.II] The shape function on physical cell in hexahedral is not parallel with the edge (FeNedelecSZ and FENedelec)

Hi all, It was a long time since the last time I posted my test for shape function in 3D here. This time I send you the results when testing with a more simple model in 2D, and the shape functions are still wrong with non-rectangle mesh. The codes print results in this form: dof i_th: 7 edge

Hi, I have written this code for testing purpose. In case of a rotated cube, the shape functions seemed to be good as they were parallel to the edge, although there was some small round-off errors at the value 0. However, when I tested with the grid which was loaded from GMSH, the shape functions

Hi colleagues, When using FE_NedelecSZ in my code. Testing for an edge whose global vertices located from (0,0,0) to (0,0,1) in real coordinates. With a cube I get the shape function vectors at the dof related to the edge, for examples, (0,0,0), (0,0,-0.25), (0,0,-0.5), (0,0,-1), which are
