- W2364336249 abstract "In this paper, we briefly introduce the basic idea and principle of the multigrid (MG) method.Then weapply the MG algorithm to the finite element method to solve 2D Poisson equation with grid scale increasing from 8 ×8 to 1024×1024.Comparison with Gauss-Sediel Iterative (GS) and conjugate gradient (CG) method in running time and iteration number, shows that the calculation speed of MG is much faster than GS and CG.With a grid of 1024×1024;the MG method is about 500 times faster than the GS method and 60 times faster than the CG method. MG is smaller than GS and CS method in error between numerical solution and theoretical solution." @default.
