Abstract

Techniques of transient analysis by the boundary-element method (BEM) using the Fourier transform are presented. In the proposed method, the response of the frequency domain is obtained by boundary-element analysis in sinusoidal steady-state analysis. Transient analysis is examined by the inverse Fourier transform using the response of the frequency domain. Therefore, the volume integral with respect to the region to be analyzed is not necessary. The applicability of the method is shown by comparison of the computation results of the 2-D model and 3-D model with the theoretical values. The time integration of the proposed method is more stable than that of the time-differential method
