I'm also curious how programmers decide to "simulate" fluid. As a person who deals with fluids regularly, it's difficult to truly appreciate how hard it is to simulate 2D fluidic flow. It takes almost weeks on 100-core machines to run true CFD simulations even with large eddy simulations. Clearly you guys don't solve Navier-Stokes, but you make it look fun and believable enough. Do you even use wave equations; do you make assumptions; do you just draw it out so it looks real?
