Frequency response of acoustic wave

Post by pironman »

Good morning, I'm new to Elmer, and new to acoustic simulation (till now I use only Code Aster and a commercial FEM with only mechanical static and dynamic simulation). I would like to simulate a pipe filled with air, open at one end and with a membrane that generate a forced frequency at the other end. That membrane must generate a range of frequency, and I would like to obtain a graph of the frequency response.
I try the tutorial 17 on this document:

http://www.nic.funet.fi/pub/sci/physics ... orials.pdf

I have to simulate a system similar to that, but except a single frequency, I would like a range of frequency, and I'm not interested in the pressure inside the cavity but only the response at the membrane.

Thanks

Instead of a single frequency use scanning to do multiple frequency, then plot in paraview
