基于MPI的不可压缩N-S方程并行计算方法

PARALLEL COMPUTING ALGORITHM OF INCOMPRESSIBLE N-S EQUATION BASED ON MPI

在目前的流体计算中,当雷诺数较高时,计算量非常巨大,存在耗时长的问题,需要采用并行计算,对此提出一种基于MPI(Message Passing Interface)的并行计算方法。通过实例验证,该方法准确、易行、稳健,并且可以大幅提高计算速度,节省计算时间,对于大型科学计算问题具有很好的适用性。

For the present CFD,parallel computation is needed because of much calculation work and long time cost in condition of high Reynolds number.Thus a new parallel computing algorithm based on MPI is put forward.According to instances attested,this method is accurate,easy and stable,with higher computing speed and less computing time,which is well adaptable to large-scale scientific computing.
