Abstract
We develop a new W-cycle multiscale multigrid method that can use the existing multilevel (different scale) grid hierarchy to approximate the sixth order solution of Poisson equation based on the fourth order discretization schemes. Richardson extrapolation procedure is used on the fine grid level in multigrid method. Numerical results are conducted to show the solution accuracy and the computational efficiency of our new method, compared to Wang-Zhang's sixth order multiscale multigrid method using V-cycle.
