Hi Erik

 

I want to perform an modal simulation to extract the modes using only the panel, then the acoustic cavity and then the system panel+ acoustic cavity.

After I want to perform an harmonic analysis to extract the sound pressure level generated in the system panel + acoustic cavity.

I don't know if the video that you sent apply for this case, because I am using the acoustic body below the panel (surface not a solid), as you can see in the image. 

 

My main goal is to extract the sound level pressure, but I'm a little bit ansure about the process. 

 

I try to do as you said using the harmonic acoustic, but i'm still get it the same ? error when trying to apply the FSI. 

I'm sending the link of the project, if you can see it would be great.
