隐式TVD有限差分算法区域分裂并行实现

A PARALLEL IMPLEMENTATION OF AN IMPLICIT TVD FINITE DIFFERENCE ALGORITHM USING THE DOMAIN DECOMPOSITION METHOD

借助静态非重叠离散区域分裂法，研究了ＨａｒｔｅｎＹｅｅ隐式ＴＶＤ差分算法在ＭＩＭＤ多机系统上的并行实现问题。通过对超超喷流流场的定常数值模拟，检验了相关并行处理的收敛性和稳定性。

Based on a static non overlapped domain decomposition method,the problem is studied about the parallel implementation of a Harten Yee implicit TVD difference algorithm on a MIMD multi computers parallel system.The convergence and stability of the parallel processing techniques used here are manifested well through numerical simulation of the steady″super supersonic″jet flow fields,and the parallel parameters obtained are promising.
