An Extension of the MAC Scheme to some Unstructured Meshes
Résumé
We give a variational formulation of the standard MAC scheme for the approximation of the Navier-Stokes problem. This allows an extension of the MAC scheme to locally refined Cartesian meshes. A numerical example is presented, which shows an efficient computation of the solution of the Navier-Stokes problem for a general 2D or 3D domain, using locally refined meshes.
