A multigrid-preconditioned Newton--Krylov method for the incompressible Navier--Stokes equations (English)
0 references
The pressure-correction methods SIMPLE and SIMPLER are adapted for use in preconditioning a matrix-free Newton-Krylov method applied to incompressible Navier-Stokes equations, as well as to some unsteady problems. The preconditioner is constructed as a smoothers of a linear multigrid procedure. The effectiveness of the resulting Newton-Krylov multigrid method is demonstrated on benchmark incompressible flow problems.
