Exploring my way into fluid dynamics. Hoping to use available tools to simulate shallow water, small amplitude wave motion.
Besides the early diewald_fluid library ("Q1 of 2"), I've downloaded PixelFlow. It has beautiful examples of diffuse flow (e.g. smoke-like particles) but I'm stumbling on setting up parameters and initial fluid surface. For example, it's clear enough I should turn off diffusion for my case.
A big help would be a hint on how to set up an initial body of water. I would then disturb it to cause height "impulse" and non-zero velocity. (Think of tossing a pebble into a pond.)
