摘要
计算空气动力学的高阶面元法中，将原来位流升力面理论中求解积分方程的问题近似改成求解一组线性代数方程组。针对系数矩阵的特点，采用与所分网络块对应的数据分配方式，并用部分选主元的Ｇａｕｓ－Ｊｏｒｄａｎ算法求逆。分别在４台和８台Ｐｅｎｔｉｕｍ１６６微机组成的并行虚拟机（ＰＶＭ）上运行。当矩阵阶达到２１００时，并行效率分别为９５．４％和９１％。
The high-rder panel method of Computation Fluid Dynamics (CFD) is to approximately turn the problem of solving an integral equation in the potential lift surface theory into solving a linear equation set. We distribute data according to its distributed network blocks because of the characteristic of its coefficient matrix, and use the partially pivoting Gauss-Jordan inversion algorithm. We run it on the Parallel Virtual Machines ( PVM) by 4 or 8 Pentium 166 machine. The result shows that the parallel efficiency is 95.4% and 91% respectively when the matrix order is up to 2100.
