A comparison of parallel solvers for the incompressible Navier-Stokes equations

In this paper we compare coupled multigrid methods and some pressure correction schemes (operator splitting schemes) for the solution of the steady state and time dependent incompressible Navier-Stokes equations. We consider pressure correction schemes with multigrid as well as single grid methods for the solution of the Schur complement problem for the pressure. The numerical tests have been carried out on benchmark problems using a MIMD parallel computer. They show the superiority of the coupled multigrid methods for the considered class of problems.
