基于 Crank-Nicolson 格式的移动网格算法求解对流扩散问题
Moving mesh method for solving convection-diffusion problems by Crank-Nicolson scheme
摘要
Abstract
A Crank-Nicolson difference scheme on moving mesh for a class of unsteady singularly perturbed convection-diffusion problem with source term was constructed,and its iterative method and algorithm were introduced.The error on moving mesh and that on uniform mesh was compared by numerical experiments,and it proved that one of the effective methods for solving singular perturbation when using Crank-Nicolson difference scheme on moving mesh.关键词
