Can we get sound pressure on octave bands using ADE modul?

Hello, i am working on project now, room modelling using acoustics diffusion equation modul. I need some parameter for my project.
I finish to get steady state sound pressure level using this modul. However, can ade modul calculate sound pressure level on octave bands? I have used the input source with input bands. It still cannot work.
Would you suggest me any way to overcome this issue?
Thank you,

Hi Ainun
You need to run a parametric sweep over the frequency band studied. Have a look at this model (https://www.comsol.com/model/20171) where the parametric sweep is done for the eigenfrequency study. You can do the same for the stationary study. The frequency dependency enters through the boundary conditions.

Hi Mads,
Thank you for your prompt reply. It is very helpful. I have followed the the model which you showed to me. However, i have the other problems. It said failed to find solution. It happen when i computed the stationary study. Do i need to define the power source in all band number?
Kind regards, Ainun Nadiroh
