The Application of Multigrid Method in the Adaptive Mesh of Acceleration Generation
多重网格法在加速自适应网格生成中的应用

The multigrid method which was developed in the 1970s is a powerful tool to accelerate the convergence of iterative It uses different mesh density to eliminate the different frequency component of errors, which accelerate the convergence of iterative It possess of the advantages with fast convergent speed, high convergent accurate and saving CPU Multigrid method was applied to accelerate the generation of adaptive mesh in this paper Experiments show that the multigrid method raises efficiency with more than twenty times compared with single grid
