Real-Time Fluid Dynamics for Games

https://www.research.autodesk.com/publications/real-time-fluid-dynamics-for-games

Stable Navier-Stokes solver for games with C code; density step: add source, implicit diffuse via Gauss-Seidel, semi-Lagrangian advect; velocity step adds projection to a divergence-free field via a Poisson solve; stable at arbitrary time steps; real time for reasonable 2D and 3D grids.
