In Comsol i want model a vibrating rigid solid makes acoustic waves in surrounded atmosphere. How can do that?

I want make a model of acoustic-solid interaction (an acoustic wave made by vibrating solid). But because of time consumption, i don't need structure analysis and it's better to model solid as a...

What is different between time dependent modal and time dependent (transient) analysis in comsol?

Hi I'm try to simulate time dependent vibration of a solid in a fluid media such as air in comsol but when i checked it, it shows a damping vibration if i use time dependent modal. for what we...

Problem in plot time dependent vibration in comsol?

Hi, when i plot the time dependent plot of a selected point of a beam (for example in w displacement), the resulted plot was true but it is not smooth enough as i expect it. i try to decrease time...
