| Abstract: | Multigrid method is a rery efficient method for the numerical calculation. This method is applied to the problems from fluid dynamics. Full approximation scheme (FAS) is tested. Multigrid method, combined with the flux- vector splitting algrithm and the finite volume technique, yields a fast and robust method for finding steady solutions of the euler equations. The satisfactory results have been obtained. |
