摘要: 给出了一种基于网格整体重分的中心型ALE方法,用于求解多介质大变形的可压缩流动问题。方法可在分区重分和整体重分之间切换,具有较强的适应性。通过静态和动态数值算例显示网格整体重分的效果,并将数值结果与分区重分的结果进行比较分析,对非常复杂的计算区域体现了整体重分的优越性。Abstract: A cell-centered arbitrary Lagrangian-Eulerian method based on a global grid generation technology was developed to simulate compressible multimaterial flows with large deformation. The method adapts well to subdomain grid generation and global grid generation. The static and dynamic numerical examples demonstrated the efficiency of the global grid generation. For the examples with complex regions, the calculated results show the efficiency of the global grid generation.
