This article is intended as a preliminary report on the implementation of a finite volume multilevel scheme for the discretization of the incompressible Navier–Stokes equations. As is well known the use of staggered grids (e.g. MAC grids, Peri´c et al.) is a serious impediment for the implementation of multilevel schemes in the context of finite(More)
In this work, we point out and apply some ideas for the numerical simulation by multi-level schemes of several wave equations including dispersive (Korteweg de Vries) and dissipative ones (Kuramoto-Sivashinski). We start from the approach developed for dissipative equations decomposing the solution into large (Y) and small (Z) scales, and we show that it is(More)
