Comparison of Some Preconditioners for the Incompressible Navier-Stokes Equations
Comparison of Some Preconditioners for the Incompressible Navier-Stokes Equations
Abstract In this paper we explore the performance of the SIMPLER, augmented Lagrangian, āgrad-divā preconditioners and their new variants for the two-by-two block systems arising in the incompressible Navier-Stokes equations. The lid-driven cavity and flow over a finite flat plate are chosen as the benchmark problems. For each problem the ā¦
