EM Transducer is a boundary condition commonly used in the simulations of MEMS devices. Workbench users can download the Piezo & MEMS ACT module from the ANSYS Customer portal to gain access to EM transduce capabilities. EM Transducer automatically generates TRANS126 elements in Workbench based on the EMTGEN APDL command.
The EM Transducer object uses permittivity of Air as a default and does not allow users to define their own permittivity. If a user wants to define a custom permittivity, they can create an APDL command object that updates the 7th real constant of the generated TRANS126 elements. See the sample code below:
