PixelPro demonstrates a technique that came out of a brainstorm while playing with Hybrido Solvers in Realflow where he is able to calculate vorticity. With vorticity data you are able to create foam and other effects in collision areas with other particle effect applications such as Krakatoa.

“As you know there is no way to calculate vorticity in realflow “hybrido solver” (realflow Grid based simulation) even though “vorticity” gives us an excellent option to create an imitation of foam activity in water collision areas by rendering with Krakatoa KCM etc. So somehow I got an idea how to do it, and it just worked ..! I hope that is clear and understandable tutorial I’m pretty sure you do not want to hear my broken English .. Or that the tutorial will be in Hebrew 🙂 Anyway… Enjoy.. :)”
