Wagner, Siegfried (ed.), Computational fluid dynamics on parallel systems. Proceedings of a CNRS-DFG symposium in Stuttgart, Germany, December 9 and 10, 1993. Braunschweig: Vieweg. Notes Numer. Fluid Mech. 50, 59-65 (1995).
Summary: A parallel vectorized finite volume method for the three-dimensional Navier-Stokes equations is presented. The solution procedure is based on collocated blockstructured grids and on an iterative pressure-velocity coupling of SIMPLE type. A high numerical efficiency is ensured by a nonlinear multigrid method. The flow solver is implemented for shared memory, virtual shared memory, and distributed memory systems based on an automatic grid partitioning technique. By considering steady and unsteady three-dimensional flow problems, the numerical and parallel performances of the solver are discussed. These studies also include a comparison of workstation clusters and classical vector supercomputers.
