摘要
将单向外推应用到有限元区域分解法 ,我们将区域分解成几个子区域 ,然后对每个子区域沿着一个方向加密网格 ,最后组合所有结果得到高精度 .这种方法有两个优点 :一是计算量小 ,二是适于并行计算 .
The aim of this paper is to apply the unidirectional extrapolation to domain decomposition method for finite element. We decompose the domain into several subdomains, then refine mesh along one direction for each subdomain, and finally compose all results to get high accuracy. This method has two advantages: one is small computational amount and the other is that the parallel calculation is possible.
