mymesh.mesh.mesh.EulerCharacteristic

property mesh.EulerCharacteristic

Topological Euler characteristic number. For volume meshes, the surface mesh is used. To prevent unattached nodes from influencing the vertex count, vertices are counted as the number of unique nodes referenced in mesh.Edges.

\[\chi = V-E+F\]

E: number of edges

V: number of vertices

F: number of faces
