Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NNFM, volume 29)


The paper reports on the use of a multigrid method for calculating 3-D incompressible, laminar flows with complex geometries. The flow solver, which is briefly described, is based on a finite-volume method using non-staggered grid arrangement and general curvilinear coordinates. Following the SIMPLE-algorithm of Patankar and Spalding the discretized momentum equations are solved sequentially. The applied multigrid method is a modified Full-Approximation Scheme (FAS), updating the variable-dependent components in the source terms on coarser grids too. For the different flow configurations the multigrid performance is described and the predicted results are presented.
