本研究旨在提昇邊界元素法計算效率。文中使用以B-木條曲線爲基礎之設計方法減少未知數之數量並降低計算量。另一方面，在更動原始邊界元素法計算程序搭配以訊息傳遞介面(MPI: Message Passing Interface)爲基礎之分散式計算系統後，邊界元素法誘導函數計算與線性系統求解之兩大計算瓶頸亦得到改善。文中提出設計實例以爲驗證，由計算實例之結果，可了解本設計方法之正確性以及分散式計算系統對邊界元素法計算效率之提昇。

In this paper, a hydrodynamic design method developed on a distributed computing system is presented. The B-spline defined geometry is used in this design method, thus the number of unknowns and computational time can be reduced. A PC distributed computing system based on message passing interface (MPI) is established, and the computations of influenced functions and solutions of the linear systems can be more efficient. Numerical examples including the design of lifting and non-lifting bodies are demonstrated in this paper. Computational results have shown the accuracy of presented method and the improvement of the computational efficiency.
