There’s a new version of the glu3D fluid motion simulator for 3dsMax that brings it up to date with 3dsMax2012 and adds in CUDA computation for improved performance.
It speeds up intensive computations that glu3D performs to calculate particle fluid dynamics. With this glu3D edition it is possible to simulate faster and with more particles than before; it is possible to simulate your scene more times; it is almost interactive. Animated fluid scenes with more quality and level of detai
You can download their free Demo version at their site, or buy it for $760.
