约束插值剖面法是一种新型的低色散数值格式。它是一种特征线法(MOC)。在过去的研究中,我们应用CIP方法对声波传播进行了数值分析。对于复杂非均匀介质的模拟或大规模的波传播模拟,一种新的网格系统是必不可少的。在这项研究中,我们研究了CIP声波模拟的子网格技术。它是澄清,这种技术具有其小的内存需求和计算时间少的优点。
The constrained interpolation profile (CIP) method is a novel low-dispersive numerical scheme. It is a kind of method of characteristics (MOC). In our past study, we applied the CIP method to numerical analyses of sound wave propagation. For simulations of complicated heterogeneous media or large-scale simulations of wave propagation, a new grid system is indispensable. In this study, we examined a sub-grid technique for the CIP acoustic wave simulation. It is clarified that this technique has the advantages of its small memory requirements and less calculation time.
