摘要
基于ＭＩＭＤ并行计算机模型，本文讨论了ＣＦＤ问题应用显式有限差分方法的并行化问题。利用区域分解法将计算问题分解为多个子问题，每个子问题由不同的处理器分别处理。针对ＳＣＢ计算格式的特点，尽量降低各处理器间的数据通讯，提高了并行计算效率。最后给出二维Ｅｕ－ｌｅｒ方程组计算实例，计算结果令人满意，且算法有较好的可扩放性。
Based on MIMD parallel computer model, parallel implementation of explicit finite difference methods has been discussed for computational fluid dynamics(CFD) problems. The present method divides the computation domain into some subdomains(sub problems) in order to solve each sub problem in someone processor. To SCB schemes, the communication of data between processors is decreased so that the efficiency of parallel computing is increased. At last, the numerical experiment for 2 D Euler equations has been given. The computing result is satisfactory, and the algorithms scalability is fine.
