Gray-Scott Reaction-Diffusion

A two-chemical reaction-diffusion simulator. Tiny changes to feed, kill, and diffusion rates can turn a seeded patch into spots, stripes, waves, or coral-like growth.

Model math
∂U/∂t = Du2U - UV2 + F(1 - U)
∂V/∂t = Dv2V + UV2 - (F + k)V

This is the Gray-Scott reaction-diffusion model. U is continuously fed into the system. V grows by consuming U, while the kill term removes V. The Laplacian terms diffuse both chemicals across the grid.
