摘要
多重网格技术是一种非常有效的数值计算方法,本文采用多重网格中FAS格式进行数值实验,计算加速效果十分明显;同时,结合矢通量分裂及有限体积法,大大提高了捕捉激波的质量。
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.
