Abstract
The three-dimensional (3D) finite-difference time-domain (FDTD) method is applied to acoustics analysis in this paper. The disadvantages of its method are large memory requirement and long calculation time. We developed the 3D-FDTD method using parallel computing with the Message-Passing Interface (MPI) in the personal computer (PC) cluster because it could shorten the calculation time and could treat larger memory. In this paper, basic algorithm of the proposed method is described. The acoustic fields of point sources and the real aerial sensor are calculated for verifying the validity of the method.
