3D More Material Euler Interface Processing Parallel Algorithm Research

摘要:

针对现有的算法无法对爆炸冲击进行有效的研究这一问题,在改进了Youngs界面技术的基础上设计了三维多物质Euler界面处理的并行算法;然后采用MPI标准进行了算法的程序设计并对程序进行了并行性能测试和不同分区的算例测试,测试结果表明并行算法对加速比有较大的提高,而不同分区对并行算法的计算结果并没有影响;最后应用所编写的程序对空中爆炸和聚能射流进行了仿真,结果表明程序的模拟结果与前人的研究数据是符合的,说明了程序的有效性。

Abstract:

Of explosion shock in view of the existing algorithms can not effectively study this problem, on the basis of the technology improved the Youngs interface design for more than three dimensional material Euler interface processing parallel algorithm. Then using MPI standard to the program design of the algorithm and program for the parallel performance testing and different partitions example test, the test results show that the parallel algorithm for acceleration is larger, the different partition has no effect on the calculation results of parallel algorithm. Finally application programs written by the air blast and shaped jet are simulated, the results show that the simulation results and the program is conform to the predecessors' research data, illustrates the effectiveness of the program. 
