PolyMAC: Staggered Finite Volume Methods on General Meshes for Incompressible Navier–Stokes Problems
Résumé
We consider new finite volume methods of staggered type for incompressible Navier–Stokes equations. These methods, called PolyMAC, generalize the MAC scheme to general meshes. We briefly describe the different versions of PolyMAC and present guidelines for an efficient use. To do so, we define a benchmark of 3D Navier–Stokes problems based on the successive benchmarks established during previous FVCA conferences. Finally, we identify weaknesses of each PolyMAC version and suggest ways to improve the current performances.
