Hybrid Finite Analytic Multigrid Method of Linear Convection-diffusion Equation

建立了二维线性对流扩散方程的混合有限分析多重网格法，计算结果与精确解吻合，为计算高维复杂流场建立了一个重要基础．同时通过计算证实了多重网格方法具有与网格参数无关的收敛性．

The hybrid finite analytic multigrid method is establlshed for 2-D linearconvection-diffusion equation. The good agreement between the calculated data and the analytical solution is got.It is an important fundament for the calculation of the highdimensional complex flow using the micro-computer. The convergence of the multigridmethod is independent of the grid parameter, which is proved by the calculation mentionedabove.
