High-Order Compact Difference Scheme and Multigrid Method for Solving the 2D Elliptic Problems
A high-order compact difference scheme for solving the two-dimensional (2D) elliptic problems is proposed by including compact approximations to the leading truncation error terms of the central difference scheme. A multigrid method is employed to overcome the difficulties caused by conventional ite...
