Applying physics to computer science Anonymous Thu Jun 30 16:34:29 2016 No.8174651 [Reply] [Original]

What sort of math is involved in a particle (fluid) simulator?

>>	Anonymous Thu Jun 30 16:36:48 2016 No.8174655 Navier Strokes equations. It's unbelieveable how accurate they are. Almost like the physics are simulated.

I can't believe that nobody has mentioned the Lattice Boltzmann model. It took me forever to write one of those programs and actually understand what was going on. I still haven't found a really good resource for learning this, but this comes fairly close as a good starting point: https://www.ndsu.edu/fileadmin/physics.ndsu.edu/Wagner/LBbook.pdf
