| 摘 要： | 给出了实现边界元并行分布计算的一种新方法。它将边界元离散节点分为与计算网络所拥有的处理机台数相对应的若干组, 以此实现任务分配, 独立地计算形成每组节点对应的离散边界元积分方程, 最后利用迭代方法行求解分布的边界元方程组。以弹性问题为例, 在Inmos T800 Transputer 系统上实现了边界元计算。验证了本文方法的可行性与有效性。

| Abstract: | Combining the characteristics of boundary element computation, a new parallel and distributed method for boundary element method is given. Using the method, the total nodes of BEM are first divided into several groups of nodes that are mapped onto the multiprocessor system, and then the boundary element computation related to each group is carried out by a processor independently. Finally, the global boundary element equations are solved by the parallel iterative solver developed herein. Numerical experiments on Inmos Transputer System have been performed to demonstrate the power of the new method. |
