How can I create a very thin fluid, moving on a surface?


Recommended Posts


In a flip-fluid simulation, I would like to create a very thin layer of fluid that moves on a wavy surface.

I decreased particle separation to 0.001 and I increased the "Particle radius scale" to 3, but the fluid is still thick. How can I decrease its thickness?


Thanks for helping.

After the flip sim, before meshing, ray the points back onto the collision geo using a Ray Sop, with the settings - Direction from: Vector (0,-1,0) and Scale: 0.9

I would be interested in other options but just tested the Ray Sop and it kind of works.
