[petsc-users] DMPlex edge/vertex orientation

2023-08-04 Thread onur.notonur via petsc-users
Hi, I'm currently working with 3D DMPlex and performing crucial calculations involving face normals and edge tangents. I've noticed that face normals are directed from support[0] to support[1]. However, I'm uncertain about the conventions for edges and vertices in relation to faces.
