A contact Eij (red) between nodes i (pink) and j (green) is shown. Let (Ni) be the neighbours of the i and (Nj) be neighbours of the j (grey). The CNb of edge (Eij) is defined asThe nodes k1, k2 and k3 (yellow) share edges with nodes i and j. The triangles k1, k2 and k3 make with Eij constitute the CNb triangles of Eij.
