Dear Tetsuo,
This means that you want to add a fem on an edge of a 3D mesh. For a 3D
mesh, you only have access to faces, not directly to edges. And even on
faces, you cannot directly define a finite element, except if it is
defined as the reduction of a 3D FEM on your faces. So, if you want to
define a separate finite element, you have to add the corresponding 1D
edges on the mesh. If you just want to select the degrees of freedom of
a 3D FEM to reduce it, there is unfortunately no pre-defined function
for that (you can of course list the dof and select them by hand).
Best Regards,
Yves

Dear GetFEM++ Project
Hello. I am trying to make 1D FEM at the corner of 3D regular mesh in C++.
I used getfem::select_faces_of_normal to set region at corner, but it
seems not work.
What is the best way to select the region at corner in 3D mesh?
Best Regard Tetsuo
