Hydrodynamics in Javascript
I'm teaching myself CFD in my free time. I'm focusing on hyperbolic solvers because they seem particularly of interest in the field of numerical relativity, which I am aiming to apply these lessons towards.

Here's what I've got so far:

1D CFD Simulation in WebGL - GitHub

2D CFD Simulation in WebGL - GitHub
2D GPGPU-driven CFD Simulation in WebGL - GitHub
