Abstract (in Japanese) (See Japanese page) 
(in English) I'll tell you about my career of numerical simulation. My center of interests is a transient analysis of solid vibrations and waves in solids. Especially I've been involved in electro-mechanical transducers. The ultrasonic oscillator is electrically driven. Therefore, when studying numerical analysis methods, it was the electrical equivalent circuit, especially the distribution equivalent circuit and the distribution constant line, that always flowed to the undercurrent. In addition, although I have always had non-linearity in my mind, it was very difficult for solid materials to have non-linearity.
