Hi

See our new topics in acoustics helps – that will show how to get started (one needs harmonic acoustic system with 2 physics regions, one for water (acoustic) and one for epdm walls (structural – can not be hyperelastic as harmonic analysis is linear – see our course in harmonic analysis)).

For vibroacoustic example similar to what you have see:

All the best

Hi

Perhaps other forum members can provide feedback.

From my side:

As we said see here and go through all the examples in detail:

Hi,

Thank you again for sharing these resources!

I’ve gone through the setup as recommended, including configuring two physics regions (water for acoustic and EPDM for structural) and applying the necessary boundary conditions. However, I’ve run into a bit of an obstacle with the material data in the Engineering Data library—I couldn’t find the required properties for EPDM and borosilicate glass (isotropic Elasticity, density,speed of sound, viscosity ... )

Thanks once more for your help and guidance!

Best regards,
Bassel
