mechano-acoustic coupling

[iczajka]

I want to analyse interior space of a rectangular box. I wonder if it is posible to have elastic walls for helhmoltz equation. Excitation is in form of acoustic pressure in particular point inside box.

So I want to analyse elastic box with sound source inside.

Do You think it is possible? And How?

I am working on a similar problem. I believe this can be done through coupled structural-fluid-acoustics (Elastic-Navier Stokes-Acoustics) technique. Not sure if you have already tackled the problem. Let me know how did it go.

Becouse I was in hurry, I did it in Ansys. So, if You find any solution, it will be appreciated.

Hi

At least hierarchical coupling from acoutic to elastic, or elastic to acoustic should be possible rather easily (when you know what you're doing...). Perhaps we could write a minimalistic example some day. Seems to be a recurring wish.
