Hi

I'm working on acoustic interaction with structures.
I've attached an image of the model that i have created.

Since im using transient pressure acoustics as the physics i cant use PML.
My first question is what boundary condition will be most appropriate.

I want to eliminate reflections from the walls.
Ive used impedance boundary condition with impedance of steel as the impedance value.
Is this right? Or should i use the cylindrical boundary condition?

My second question is :-Can i place the probe point on the boundary to test for the pressure?
Will the boundary condition override the pressure that the point will receive.

This problem is generally with boundary conditions regardless of physics.
This problem ive been facing with the rf & structural mechanics as well.

Thanks a lot for your time and effort.

Regards
Glenston
