Background, Motivation and Objective In recent years, time domain-numerical analysis for sound wave propagation has been investigated widely as a result of advances in computer technology. The development of accurate numerical schemes is an important issue. A method of characteristics (MOC) is used as a time domain numerical analysis method, examples of which are the constrained interpolation profile (CIP) method, and the QUICKEST method. However, new grid systems are required for the numerical simulation of large-scale simulations of wave propagation. To overcome these problems, we introduce the non-uniform grid system for the scheme combining multi-moment-MOCs, the Hybrid MM-MOC, with perfectly matched layer (PML) technique.
