Help Wave effect on fluid surface

[josemendez]

The problem is that I need to clear the surface from the fluid when an interaction with another object happens (as you can see on the left of the image of the previous post). I think the particle-based is better, no? So is there no way to make a movements on the surface?

I don't think I understand...what do you mean by "clear the surface from the fluid"? Do you want certain regions of the fluid to disappear?

Particle based approaches calculate fluid dynamics for the entire volume of fluid. Think of particles as water "atoms". This is good for topological changes and complex fluid interfaces, but very expensive. If you're only interested in the surface, I see no reason to use a particle-based system. Calculating only the surface dynamics is orders of magnitude faster.
