Abstract:

This paper presents a composite multigrid method and its application to a geometrically complex flow. The treatment of the interior boundary boundary conditions within a composite multigrid strategy is described in detail for a 1-D model equation. For the Navier-Stokes equations, a staggered grid technique is adopted for spatial discretization and a fractional step method is used for the time advance. Lid driven cavity flows are used to demonstrate the effectiveness of the method.
