*Dear friends:
I need a quick algorithm to find the common faces of polyhedrons meshes for the finite volume computation. Each plolyhedron is recorded with the indexes of its six vertices(hexahedron) or four vertices(tetrahedron). Each polyhedron has only one common face with its neighboring polyhdrons.
The common face can be obtained by a slow comparison procedure, if two faces have the same set of indexes, then it is a common face between these two polyhedron.But the mesh system is too large, it will need a long time to find all the common faces.
Could you please suggest me a quick algorithm to find all the faces.
Regards
Your Sincerely*
