摘要: 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,并得到了较好的并行参数

关键词: 区域分裂法, TVD格式, 并行计算

Abstract: 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.

Key words: domain decomposition method, TVD scheme, parallel computation
