GPU-Based Flow Simulation with Complex Boundaries

We have improved the implementation on the floating point pixel pipeline on the newest generation of GPU, using OpenGL and Cg, with many new optimizations and accurate boundary condition treatment. Preliminary results show that the speedup is about 10X on a Nvidia GeForceFX 5900 Ultra vs. a Pentium IV 2.53GHz CPU.

Here are two video clips recorded in real time.
