| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, time domain-numerical analysis for sound wave propagation has been investigated widely as a result of advances in computer technology. 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. We used the MOCs for numerical analyses of sound wave propagation in an earlier study. However, new grid systems are required for the numerical simulation of complicated heterogeneous media or large-scale simulations of wave propagation. Additionally, for multidimensional analysis, the high-efficiency outer absorbing boundary is also required. To overcome these problems, we introduce the non-uniform grid system with perfectly matched layer (PML) technique. The purpose of this study is to evaluate these techniques for two-dimensional (2D) sound field numerical analysis using the MOCs(the CIP method, and the QUICKEST method). The results indicate that these techniques for MOCs have advantages of small memory requirements and faster calculation by easy implementation. |
