运用嵌入式自适应网格技术来提高结构网格求解复杂流场的分辨率。该方法根据流场的形成,将密集网格嵌入到物理量剧烈变化的区域,使求解精度得以提高的同时,避免较大的计算开销,从而达到求解效率和求解精度之间的平衡。 P V M 平台使得被嵌入的网格可以在网络中不同的机器上完成,大幅度降低了墙上时间。原始网格与被嵌入网格之间数值通量守恒的实现增强了该方法在捕捉间断时的有效性和可靠性。
Using Embedded Adaptive Grid Technique to Improve the Resolution of Complex Flow Field Using Structure Grid. According to the formation of the flow field, the method embeds dense grids in the areas with drastic changes of physical quantities, which can improve the solution precision and avoid the large computational overhead, so as to achieve the balance between the solution efficiency and the solution accuracy. The P V M platform allows embedded grids to be completed on different machines in the network, dramatically reducing wall time. The conservation of the numerical flux between the original mesh and the embedded mesh enhances the effectiveness and reliability of the method in capturing discontinuities.
