Finite-Difference Time-Domain Methodtals of the FDTD method are described. In the FDTD method, several error factors caused by discretization of sound field are pointed out. As methods to solve such problems, in Sect.?., the compact finite difference is described in detail. The FDTD method can not only be applied to acoustic problem o

Masaatsu Takehara,Naoya Hasegawathod is characteristic in that the method is in principle freefrom numerical dispersion. The characteristic allows simulations with high phase accuracy. The FVTD method is constructed on an unstructured grid system. The?method thus has an advantage in modeling complex geometries compared to the FDTD
