Multiphysics Simulation using Directly Coupled-Field Element Technology - ANSYS

As companies strive to produce innovative and higher quality products, simulation of individual physics is no longer adequate for the design of many products. Engineers and designers are continuing to employ Multiphysics simulation to evaluate their designs operating under real-world conditions.

This presentation by ANSYS, Inc. will focus on directly coupled-field element technology. Coupled-field elements can be used to solve many different types of Multiphysics problems. Analysis examples include: thermal-electric coupling, Piezoelectricity, Piezoresistivity, thermal-electric-structural coupling, and electroelasticity to cite a few examples. Physics coupling is accounted for by calculating the appropriate element matrices (matrix coupling) or element load vectors (load vector coupling) to account for the interaction between the different physics disciplines. Many products including; transducers, sensors, micro-electromechanical systems, thermoelectric coolers and electronic devices require a coupled-field simulation and can utilize coupled-field element technology.

The presentation will also highlight a number of real-world examples and customer applications to demonstrate the industry application of the coupled-field element technology. Senior development staff members from ANSYS, Inc. will also be available to address any questions about coupled-field elements and Multiphysics solution technology.

Coupled-Field Simulation - Wilcoxon Research

Wilcoxon Research is the world leading manufacturer of accelerometers, shakers, and underwater acoustic sensors for industrial and military applications. Most of our transducer designs are piezoelectric based. To design and analyze a piezoelectric sensor requires a coupled-field simulation. Two examples are given in this presentation to demonstrate how we extract the characteristics of a piezoelectric sensor by using ANSYS Multiphysics. The simulation examples involve piezoelectric and acoustic-structural coupled-field elements. Predicting the performance of a sensor greatly benefits the product design and development.
