Ansys Acoustics analysis with JCA model

This video shows how to get a Transmission Loss (TL) of a perforated media (glass wool) using the JCA model.
All walls are defined as a rigid wall condition.
And then sorry, this video has some errors (contact condition, Port of source).

Hi, thanks for great video
I just have one question, what does Viscous and Thermal Characteristic Length mean? I am trying to do similar analysis but I dont know what sould I input into these parameters.
Thank you

This is a very interesting tutorial, when I run this tutorial I got the following error similar to your video.
“The input power at the driven port is zero” same as in your video tutorial at 13:20.
How can I fix this error?

Thanks for sharing. Very useful material indeed!
I've got a related question, I modelled two chabers and a concrete wall between to see the sound isolation. However, I am forced to choose a rigid zone and i cant select the concrete wall as acoustic zone to have the sound transfer inside the wall, yet here you have 3 objects and all bodies are acoustic and no rigid body eith solid element described. What would be the problem of my model that I can't have all bodies as acoustic region?
