Abstract
Several solution acceleration techniques, used to obtain steady-state CFD solutions as quickly as possible, are applied to an upwind Euler s cheme to evaluate their effectiveness. Generalized minimal residual (G MRES), multigrid (MG), and ADI are compared to a four-stage Runge-Kutt a scheme using several grids. The use of different acceleration scheme s combinations of produces a complementary effect: the convergence bec omes relatively independent of both size and quality of the grid.
