[Libmesh-users] Elements sharing common vertex/edge

[Amneet B. <mai...@gm...>]

Hi Folks,

I am working with triangulated surfaces in 3D, and I need to:

1) Calculate angle-weighted normals at the vertex points, and

2) Calculate average of normals of two triangles sharing an edge.

For both cases, I think I would need to know all elements sharing a common
vertex, and two elements sharing a common edge, respectively. Can this
information extracted from libMesh? I am reading *.msh triangulated mesh
generated by GMSH through libMesh, if this information helps.

Thanks,
