Laplace formulations are weak formulations of the Navier-Stokes equations commonly used in computational fluid dynamics. In these schemes, the viscous terms are given as a function of the Laplace diffusion operator only. Despite their popularity, recently, it has been proven that they violate a fund

The paper compares two dierent two-grid ®nite element formulations applied to the Navier±Stokes equations, namely a multigrid and a mixed or composite formulation. In the latter case the pressure is interpolated on a coarser grid than the velocity, using mixed elements instead of mixed interpolation
Some methods are proposed for solving the Navier-Stokes equations for two-dimensional, incompressible, flow using the velocityvorticity formulation. The main feature of the work is the solution of the equation of continuity using boundary-value techniques. This is possible because both of the veloci
