fire simulation using CUDA

This a simulation of a methane flame running at ~17 fps. The simulation model is based on Navier-Stokes equations and uses chemical equations from thermochemistry for combustion modelling. Model is applied to a 64x64x64 hexahedral cell grid. This program uses Nvidia's CUDA API to accelerate fluid dynamics solver kernels, and a volume renderer. The algorithms for the fluid solver are based on the article "Real-Time Simulation and Rendering of 3D Fluids" in GPU Gems 3. The volume renderer is a modified version of the one found in the CUDA SDK.

This is only a rough demonstration of the simulation. The current combustion model is unstable, and the rendering is not very smooth. This program is part of a larger project that will incorporate gas and solid fuels.
