No worries - can you also add inline images of your model with BC, loads,.... also state which version (2021 R1?) you are using and if your are using act mem/ or acoustic extensions or not. Also any command snippets.

Also have in mind that this (piezo acoustics) can be done now in coupled field harmonic 2021 R2 release so without any snippets.

Thank you
