摘要
在交替迭代思想的基础上,提出了一种求解长条型内边界的外区域上双调和方程的区域分解算法,这种算法,通过作椭圆型的人工边界把原区域分成有界子域和无界区域两部分,利用重叠型区域分解算法—Schwarz交替法进行求解。此算法能大大缩小计算区域和减少计算过程,对求解长条型外问题十分有效。
Based on the alternate iteration thought,this paper proposes a kind of elliptic artificial boundaries over-lapping domain decomposition algorithm-Schwarz alternating algorithm in elongated domains. This method di- vides the domain into two parts ,bounded and unbounded domains, using the overlapping domain decomposition algorithm-Schwarz alternating algorithm for solving. This algorithm can greatly reduce the calculation region and the process ,and it is also very effective to solve exterior problems in elongated domains. Key words:
