Hi all,

I am trying to observe the wave propagation inside an air-filled geometry. The idea is to observe the reflection and dissipation of the waves through time and along the geometry. In my approach the excitation was given as step displacement of one wall in my geometry. There is no output, all the other walls have the boundary conditions as stationary wall defined.
My doubt is which kind of steady-state simulation should I run to use the result in the transient one?

Can anybody help me? I will be also grate if I receive some tip!

Thanks
