摘要：
We introduce a multigrid algorithm to solve the convection-diffusion equations using a nine-point compact difference scheme. We test the efficiency of the algorithm with various smoothers and intergrid transfer operators. The algorithm displays a grid-independent convergence rate and produces solutions with high accuracy. Numerical results are presented to validate the conclusions. (C) 1997 Academic Press.
