Modeling Piezoelectric Devices in Mechanical with the Piezo and MEMS ACT | Tips & Tricks

Piezoelectric modeling is not natively supported in the most recent version of Mechanical (version 2019 R1). There are two ACT extensions available on the customer portal that greatly facilitate modeling of piezoelectric devices. The first of these is the Coupled Field Physics ACT, supporting Workbench versions 17.0, 17.1, and 17.2, and 18. The second is the Piezo and MEMS ACT, supporting Workbench versions 17.0, 17.1, 17.2, 18, 19, and 19.1. 

Without these ACTs, the conversion of purely structural models into those including piezoelectric bodies would require the use of APDL commands objects. This presentation will focus on Tips and Tricks pertaining to the use of the Piezo and MEMS ACT to model piezoelectric devices. Of the two, this ACT appears to be the one more widely used for this purpose. While most of the more challenging aspects of piezoelectric model setup have been addressed by this ACT, there remain MAPDL-supported piezo-relevant features that require the use of commands objects. Modeling strategies, both those fully supported by the ACT and others requiring APDL commands objects, will be discussed. Working examples will be presented.


1. Description of piezoelectric phenomena, examples of applications
2. Piezoelectric material property definition
