MSAFluid (2009)
MSAFluid is an opensource library for solving and displaying real-time fluid simulations based on Navier-Stokes equations and Jos Stam’s paper Real-Time Fluid Dynamics for Games. It was inspired by the brilliant Plasma Pong (even with some advice by the author, Steve Taylor)..
You can play with an online interactive Java version here.

A lot of the fluid solving algorithms are from Jos Stam’s paper. I tried to wrap it up in an easy to use API to provide methods for adding & getting forces and color at any position. Other useful resources and implementations I looked at while building this lib are:
* Mike Ash (C) - http://mikeash.com/?page=pyblog/fluid-simulation-for-dummies.html
* Alexander McKenzie (Java) - http://www.multires.caltech.edu/teaching/demos/java/stablefluids.htm
* Pierluigi Pesenti (AS3 port of Alexander’s) - http://blog.oaxoa.com/2008/01/21/actionscript-3-fluids-simulation/
* Gustav Taxen (C) - http://www.nada.kth.se/~gustavt/fluids/
* Dave Wallin (C++) - http://nuigroup.com/touchlib/ (uses portions from Gustav’s)
and some other Stam solver implementations I’ve come across since writing this are:
* Chris Sugrue & Arturo Castro (C++) - http://csugrue.com/code/?p=15
* Alain Ramos (C++) - http://code.google.com/p/ofxding/downloads/list

* NVidia (C / Cg) - http://developer.download.nvidia.com/SDK/9.5/Samples/gpgpu_samples.html - gpgpu is the future
