| Abstract: | This paper introduces a procedure to solve steady 3-D incompressible N-S equations in primitive variables using HFAM with FAS-FMG.The complex flows in cavities are used as the standard problems for testing the numerical codes.The calculation results illustrate that the algorithm developed in this paper exhibits grid-independent convergence properties and that it is can asymptotically optimal iterate method. |
