Application of memory-saved time domain BEM to simulation of ultrasonic wave propagation

Abstract

A time domain boundary element method (T-D BEM) is discussed for the visualization of ultrasonic wave fields. The T-D BEM needs considerable computational memory capacity because of a stepby-step time marching calculation. To save the memory size we introduce an interpolation method into the calculation of coefficient matrices (fundamental solutions). The advantage of the memorysaved technique is shown in the scattering analyses. In this study, the memory-saved technique is then applied to a dynamic water-solid coupling problem.
