This paper presents a parallel multigrid solver for the computation of steady compressible inviscid flows around 2D and 3D aerodynamic configurations, on MIMD distributed memory machines. It is a parallel version of a large CFD code, ZEN Flow Solver, developed by the Italian Aerospace Research Center (CIRA). The sequential solver uses a multiblock structured grid and a cell-centered finite volume scheme, and implements an explicit time-marching procedure, based on a Full Multigrid algorithm. The parallel version has been developed using a domain decomposition technique, based on the multiblock structure of the grid. Moreover, a convergence criterion has been introduced in the multigrid algorithm. The parallel solver has been implemented using the PVM communication environment. Experiments have been carried out using a Convex Meta Series, a cluster of HP PA-RISC workstations. Numerical results and parallel efficiency concerning a 2D and a 3D test case are analysed here.
