Abstract: For the present CFD, when we try to solve large-scale science computing problems, such as the N-S equation, we have to calculate a lot of things and it takes a lot of time to get all the calculations done . To solve the problem, a parallel computing algorithm called MPI, which includes the solution of tridiagonal matrix and SOR, is proposed This method has been proved to be accurate and reliable, it can shorten the calculating time enormously and is well adaptable to large-scale scientific computing.
Key words: CFD, N-S Equation, MPI, Parallel Computing
摘要: 在目前的计算流体力学问题中,当求解N-S方程等大型科学计算问题时,存在着计算量大、耗时长的问题,对此提出了一种MPI并行算法,其中包括并行求解三对角矩阵与超松弛迭代。通过实例验证,该方法准确、可靠,并且可以大大缩短计算时间,对于大型科学计算问题具有很好的适用性。
