A multigrid method for recirculating flows

The use of multigrid methods in complex fluid flow problems is recent and still under development. In this paper we present a multigrid method for the incompressible Navier-Stokes equations. The distinctive features of the method are the use of a pressure-correction method as a smoother and a novel continuity-preserving manner of grid coarsening. The shear-driven cavity problem is used as a test case to demonstrate the efficiency of the method.
