A Comparison of Parallel Solvers for the Incompressible Navier{Stokes Equations
نویسنده
چکیده
The paper compares coupled multigrid methods and pressure Schur complement schemes (operator splitting schemes) for the solution of the steady state and time dependent incompressible Navier–Stokes equations. We consider pressure Schur complement 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.

A Comparison of Three Solvers for the Incompressible Navier-Stokes Equations
Three solvers for saddle point problems arising from the linearization and discretization of the steady state incompressible Navier–Stokes equations are numerically studied. The numerical tests are based on nonconforming finite element approximations of lowest order in two–dimensional domains using isotropic meshes. The investigated solvers are coupled multigrid methods with Vanka–type smoother...

Coupled multigrid methods have been proven as eecient solvers for the incompressible Navier{ Stokes equations in recent benchmark computations ST96a]. This paper presents a numerical study of two classes of smoothers in these methods. The class of Vanka{type smoothers is characterized by the solution of small local linear systems of equations in a Gauss{Seidel manner in each smoothing step wher...

In this paper we discuss preconditioners for the incompressible Navier-Stokes equations. In combination with Krylov subspace methods, they give a fast convergence for the solution of the Navier -Stokes equations. With the help of numerical experiments, we report some new findings regarding the convergence of these preconditioners. Besides that, a renumbering scheme for direct solvers and ILU pr...
