Good morning, I'm a university student and as a thesis I'm trying to simulate a silencer and see that the output is compatible with engine homologation.
I am doing this simulation with the ansys application, more specifically with harmonic acoustic of ansys.
we say that the various parameters to put I have understood them, but I do not know how to show that I have in some points 3 different layers of material, i.e. a first layer inside the stainless steel sheet, a second layer of sound absorbent and a third layer of stainless steel sheet. I am using practically the full fluid, that is, where the fluid passes in the various chambers, so I have only one body, which I formed by drawing with fusion, so I with the parameters that gives me ansys in the simulation can put in a face or the acoustic impedance of the stainless steel or a absorption coefficient of the absorbent phono, but no more parameters in the same face.
That said even if I try to draw the plates and the sound absorbent, it seems that nothing changes.
I hope to have been clear and thank you so much in the meantime!
