Reaction-Diffusion for a supply chain

Simulate a supply chain live in your browser. This runs the real Reaction-Diffusion solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Reaction-Diffusion (Gray-Scott)Live

Controls

Presets

Two chemicals diffuse and react by the Gray-Scott equations. Different feed and kill rates spontaneously form spots, stripes, and mazes — the mechanism Alan Turing proposed for animal coat patterns.

Governing equation

Reading this result: High feed (F=0.0545): abundant substrate lets spots grow and merge into branching maze and coral networks.

About this simulation

The full Reaction-Diffusion tool models a supply chain with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a supply chain?
Open this page and use the live Reaction-Diffusion tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a supply chain from your own measurements.
