Pairs the directed halffaces of a volmesh to the corresponding edge (u, v) of the dual network.
volmesh (VolMesh) – A volmesh object representing a polyhedral force diagram.
network (Network) – A network object representing a polyhedral form diagram.
dictionary – A dictionary of u_hfkey-(u, v) pairs.
u_hfkey is an interior halfface of the volmesh that belongs to volmesh.cell[u], which points to volmesh.cell[v]. In another words, its pair (or opposite) halfface belongs to volmesh.cell[v].
