| 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. |
