摘要
Parallel multigrid computations for high Reynolds Steady-state incompressible enterring flows and recirculating flows Navier-Stokes equations are organized in this paper.Based on the existed successful serial algorithms, combined with the typical numerical examples, we carefully analyzed the decrements of numerical convergence rates and the increaments of parallel efficiencies owing to the introductions of Schwarz parallelizations suitable for grid partitioning to obtain large granularity parallelism. Detail parallel numerical performence results
