Hello Peter,

I am also working on acoustic transmission loss analysis of a muffler & want to model the same in ansys,

I have also gone through tutorial PPT available on ansys website but that was for only simple muffler where they have modeled air cavity as solid & given the air parameters in ANSYS,

For this simple geometry this approach is ok but practically, we have mufflers with complex geometry which include Baffles, perforated pipes, partitions etc. so to model this in ANSYS i am seeking for help. As i am just a beginner in ANSYS therefore request you to please share any tutorial/method to model the same in ANSYS.
