      Hello, I am trying to perform a static structural analysis of a capacitive micromachined ultrasound transducer (basically a tiny parallel plate capacitor with a flexible top electrode and a fixed bottom electrode) using 2019 R3 + Piezo and Mems ACTx. I apply a 15V difference and expect to see a membrane deflection, however there is no deformation in my solution. I have not been able to figure out why and any insight would be appreciated!

      This is my model:

      In case anyone else has a similar issue, I was able to resolve it by manually increasing the number of substeps. n
