A compressible, two-dimensional, unstructured-grid Navier-Stokes solver has been developed for subsonic viscous flows. Pseudo-time preconditioning is applied to improve low Mach number convergence for primitive as well as conserved variables. The scheme was implemented on a workstation and on the Ncube2s, which utilizes the multiple-instruction, multiple-data (MIMD) approach to parallel computing. A detailed description of the implementation procedure for an unstructured-grid flow solver on a MIMD computer is given. Test cases include steady as well as unsteady flows.
