Hi, I am using COMSOL multiphysics for my acoustic simulation. I want to simplify the the pressure acoustics equation by making some variable value zero. Can anybody please tell me how to that? Thank you.
As an alternative, you may input 0, 1 or a function in the value field of that variable which you want to simplify/modify. That value field can be hidden in another physical sub-domain or in Material properties, etc.
You can enable extended equation view by clicking in show window "equation view" as said Jules Lloyd Hammond. But in your picture is already enabled. Just click on equation view end of physics interface.
