摘要：

The constrained interpolation profile (CIP) method, a kind of method of characteristics (MOC), is a novel low-dispersive numerical scheme. In an earlier study, we applied the CIP method to quantitative analyses of sound wave propagation. A new grid system is important for simulation of complicated heterogeneous media or large-scale simulations of wave propagation. In this study, we examined a sub-grid technique for use with acoustic wave simulation using type-C and type-M CIP methods. Results clarified that this technique has advantages of small memory requirements and faster calculation.
