CBS 613: COMPUTER LAB III (Stable Spatial-Temporal Patterns)

Schnakenberg Model is a model of reacting and diffusing chemicals which evolves stable spatial patterns. Model involves two reacting species.

Chafee-Infante Model A simple model used to show that a sole nonlinear Rx-Diffusion model can evolve stable patterns. Decreasing diffusivity increases the pattern complexity (illustrates how small diffusivity can be important).

Gray-Scott Model Involves three chemical species. In general, more complex patterns are possible with more species (not always). Here, stable spatial-temporal patterns emerge!
