Summary:

A Reynolds-averaged Navier-Stokes solver based on unstructured mesh techniques for analysis of high-lift configurations is described. The method makes use of an agglomeration multigrid solver for convergence acceleration. Directional agglomeration and implicit line-smoothing is employed to relieve the stiffness associated with highly stretched meshes. A GMRES technique is also implemented to speed convergence at the expense of additional memory usage. The solver is parallelized on shared and distributed memory machines using the MPI message passing library. Convergence and scalability results are illustrated for various high-lift test cases
