mechanics + Helmoltz resonnance

[frette_des_bois]

Hi,
I am trying to use Elmer for a modelization of an acoustic guitar.
I saw that there exists example of simulation of a 3D beam and fluid interraction.
And a tuning fork too.
-
But perhaps exists somewhere an example of vibrate plate of a cavity and the associated Helmoltz resonnance ?

Tx for your infos

And i am trying to clear the 3D orthotropic mechanical behaviour which seems not so easy to work with ...
