Abstract :
Fluid simulation has been an active research field in computer graphics for the last 30 years. Stam´s stable fluids method, among others, is used for solving the equations that govern fluids (i.e. Navier-Stokes equations). An implementation of stable fluids in 3D using NVIDIA Compute Unified Architecture, shortly CUDA, is provided in this paper. This CUDA-based implementation also features the accurate physical treatment of internal (i.e. static boundaries inside the simulation domain) and moving boundaries. The performance gains of the presented implementation vs a sequential CPU-based implementation, and points of further improvement are also addressed.
