Abstract:
By using different mesh densities to eliminate different frequency components of errors, the multigrid method can accelerate the convergence of iteration. It has advantages of high convergent speed and high accuracy. The multigrid method is compared with the super relaxation iteration method. Experiments show that the multigrid method performs better in improving the validity in the iteration.
