摘要
把Rodrigue和Wolitzer(1995)提出的一种新型显格式应用于热传导方程有限差分区域分裂算法的内边界点,并得到这类显—隐算法的收效性结果。新算法的逼近阶较好,而且较纯新型显式方法可以节省一倍左右的计算量。
An explicit scheme of new type developed by Rodrigue and Woltizer (1995) is used to the interface points computation for the finite difference domain decomposition algorithms for the heat equation, the result of convergence of such explicit-implicit algorithm is also obtained in the note. The approximation order of the new algorithm is better,and theoritical speedup is about 2 when comparing the new algorithm with that by Rodrigue and Woltizer.
