Abstract
A portable parallel implementation of a fractional step method to
solve 3D unsteady incompressible Navier-Stokes equations on MIMD
machines is described. The context currently considered involves
uniform grid spacing in one of the directions. A parallel
decomposition strategy and its implementation on a portable
parallel programming system (Charm) is described. Some
optimizations including one that reduces the cost of parallel
convergence tests are described. Performance results for
calculation of flow in a driven cavity on different parallel
computers are presented.
