Hello!

Does anyone of you know how to approach the cymatic look in liquids?

I have seen a thread about chladni patterns with points, but for liquids the motion and the general approach seems to be different.
The Patterns in general look different. Maybe one of guys can help me out, I'm trying to displace a grid based on the input frequency.

Here is a video reference on how it behaves in real life:

Thanks in Advance

You could ask Diego about his technique found here.

You might not need a FLIP sim to realize something similar to your reference. Check out the ripple solver.

Not sure if what you need is possible with the new Kelvin Wake deformer, but have a look.
