A Three Dimensional Multigrid Reynolds-Averaged Navier-Stokes Solver for Unstructured Meshes
Abstract
A three-dimensional unstructured mesh Reynolds averaged Navier-Stokes solver is described. Turbulence is simulated using a single field-equation model. Computational overheads are minimized through the use of a single edge- based data-structure, an efficient multigrid solution technique, and the use of multi-tasking on shared memory multi-processors. The accuracy and efficiency of the code are evaluated by computing two-dimensional flows in three-dimensions and comparing with results from a previously validated two-dimensional code which employs the same solution algorithm. The feasibility of computing three- dimensional turbulent flows on grids of several million points in less than two hours of wall clock time is demonstrated. Multigrid, Unstructured, Navier- Stokes
