Hi Erik,

Thank you very much for your answer! That looks really cool. I am still unsecure which geometry feature to choose to apply the pressure: If I select any vertice of the fluid-solid-interface for example, is this static pressure (process pressure) applied to the whole acoustic region (fluid region)? In terms of structural analysis I would say no, but in terms of pressure as an intense quantity (meaning that it is the same in any connected fluid region) I would say yes.

All the best!
