Spherical Piezoacoustic Transducer
Application ID: 6210
This tutorial provides a step-by-step instruction to setup a fully-coupled 3D structural-acoustic interaction problem. Interaction between a vibrating spherical piezoelectric structure with the surrounding fluid media is considered. The piezoelectric material PZT-5H from the materials library is used. Instructions on how to create a radially polarized piezoelectric material in spherical coordinates is provided. Symmetry planes are used to obtain a reduced modeling geometry. The effect of excitation frequency on model geometry and mesh is discussed. Perfectly Matched Layer is used for modeling an infinitely extended air domain. The coupled multiphysics is solved as a stationary problem by considering frequency domain analysis.
