Driven/Travelling wave vibration of a flat plate. FSI problem.
 
I am trying to simulate the flat plate and fluid interaction, however, unlike most of the cases, the "vibration" is a continuous sine wave.

In the experiment, the flat plate is meant to be driven such that each crest and trough are pulled on either side and rolled in order to achieve the continuous wave, however, I am struggling to find a way to simulate that, if I use FSI.
If I go the dynamic mesh route in fluent, I don't know whether a varying geometry can work, I have seen examples of valves and piston moving, but they all have fixed geometries.

I also used COMSOL, however the excitation of the plate turned out to be quite inaccurate(using a simple sine pressure load). There are other ways, for example physically applying time dependent loads across the plate and do a fsi then, but I don't really know if that's the right approach.
