Houdini 13 features an updated version of its FLIP (fluid-implicit particle) solver Bifröst is already a very impressive fluid simulation system, with more yet to come. However it does have the ability to produce velocity fields from displaced geometry and have that affect the particles, to produce rolling waves, for example.
It's capable of handling tens of millions of particles for large-scale fluid simulations, although it doesn't yet create foam and spray. A year later, Naiad resurfaced as Bifröst – the procedural effects platform in Maya 2015. Naiad never even made it to version 1.0 before Autodesk bought the technology in August 2012. Although unfinished, the technology was employed as a dedicated tool for VFX studios and was used in films including Avatar, X-Men first Class, Rise of the Planet of the Apes. One app that caused quite a stir in the fluid scene was Naiad from Exotic Matter, which first appeared around 2009 in some mazing SIGGRAPH tech demos.
