摘要: In this paper a parallel flow solver for the execution of three-dimensional simulations on unstructured meshes is presented. The Euler/Navier-Stokes equations are discretized by means Finite Element Technique based Galerkin approach. implementation has been executed decomposition mesh domain into set subdomains to be assigned processors machine; code developed using MPI environment as message passing software. test case considered simulation around M6-wing with tetrahedral mesh. Parallel performances obtained SGI Power Challenge supercomputer will given; moreover, importance an efficient partitioning algorithm highlighted.
