GPU-based Smoothed Particle Hydrodynamics using CUDA, Test scene 3

A video demonstrating my GPU-based Smoothed Particle Hydrodynamics (SPH) implementation using CUDA to achieve extremely high performance.
The video shows the real-time performance of the implementation, more than 100 FPS (dt=0.002) is achieved on a NVIDIA Geforce GTX 470 (Fermi).
In this scene a water-like fluid is simulated using a SPH model described by Mueller in "Particle-Based Fluid Simulation for Interactive Applications".
Test scene 3, 128K particles and hue-based color gradient for particle velocity.
This work is part of my masters thesis in computer science at NTNU (Norwegian University of Science and Technology).

nice.

what we need is a good virtual windtunnel where you can load a mesh and get accurate data about its aerodynamics. preferably GPU based

I have no idea what any of that means or why I'm watching this. ._.
