摘要 将奇异摄动对流扩散问题的区域分解算法推广到二维非定常的情形,并将Shishkin混合有限差分格式与区域分解方法结合,得到了此类方程更高精度的并行算法。 This paper develops the domain decomposition method(DDM) to solve the time dependent singular perturbed convection-diffusion problems.Based on a Shishkin hybrid difference scheme coupling with the domain decomposition method,a high accuracy parallel algorithm is presented for the above kind problem.
