Implementing BCs for a travelling wave wall in Fsi

Please login with a confirmed email address before reporting spam

Hello,

I was a Fluent user till recently, but I needed more to couple multiple physics, still getting used to Comsol.
At the moment it's just Fsi.
For simplicity sake, I have 4 walls; an Inlet, an outlet, a fixed wall and an oscillating wall(shared wall with the material).
I am trying to have a travelling sine wave on this wall whilst fluid reacts to this oscillation.

I am wondering how should I do for a time dependent study, I have tried giving moving loads from the example peristaltic pump, and on another instance, using waveform and analytical expressions. I am not able tie up anything with Timestep and frequency of the travelling wave.

Are there any guides or another examples that I may have missed? Or, perhaps some can help directly, that would be grateful.
