A comprehensive Finite Element based code will be developed for the simulation and design of piezoelectric transducers. The code will permit complete, three- dimensional, time-domain finite element modeling of waves in piezoelectric-elastic-acoustic media. An existing Weidlinger Associates Finite Element program provides the basic frame work. During Phase I, piezoelectric and acoustic-potential finite elements will be added to the base code resulting in a global two and three-dimensional simulation code to model ultrasound-type transducers.

将开发基于有限元的综合代码，用于压电换能器的仿真和设计。 该代码将允许对压电弹性声介质中的波进行完整的三维时域有限元建模。 现有的 Weidlinger Associates 有限元程序提供了基本框架。 在第一阶段，压电和声势有限元将被添加到基本代码中，从而产生全局二维和三维仿真代码来对超声型换能器进行建模。
