摘要: 研究了用于处理三维多物质欧拉网格的模糊界面技术以及算法存在的数据相关性问题,提出了解决数据相关性的方法。采用基于消息传递接口(MPI)模式,设计出了相应的MMIC-3D并行程序,得到了无限空气介质中爆炸的三维数值模拟结果,计算结果与实际的实验现象及规律基本吻合。在共享存储的全对称多处理机(SMP)上进行了测试,得到了理想的加速比。Abstract: Euler algorithm, fuzzy interface method for three-dimensional multi-material and the data dependence of this algorithm were studied, and a method for settling the data dependence was presented. The parallel program of MMIC-3D based on message passing interface (MPI) was designed. The three-dimensional numerical simulation results of explosion field in an infinite air medium, which were obtained in this study, are in agreement with the experimental phenomena and the principle of physics. Test on the symmetrical multi-processing (SMP) shows a better speedup.
