### Why FVM can handle unstructured meshes while FDM cannot?

The difference between finite volumes and finite differences is really more about the form of the equations solved. In typical FV methods, the conservative form is ...

### Mesh ordering algorithms used by COMSOL Multiphysics

The idea of "ordering the nodes" in a finite element mesh to improve the computational time of the sparse solver originated in the large structural analysis FE codes of the 70's. Those codes typically ...
