Entagma is back with another great Houdini guide.

Entagma is back with another great Houdini guide. This time, Moritz Schwind shows how you can generate Rayleigh-Taylor instability inside the tool. The artist presented a pretty simple setup that will let you get some amazing fluid swirls with cool details. 

This was one of the questions we received while on season break: How would we go about creating a Rayleigh Taylor instability. After quickly brushing up on our fluid dynamics knowledge and conducting quite a funny real-world experiment (“Let’s see if this really works!”), which involved microwaving dye, we came up with a pretty simple setup that nevertheless generates quite amazing detail in the fluid swirls that are so typical of the phenomenon called Rayleigh Taylor instability.
