How do I simulate a bouncing ball?

Open this page and use the live 3D Heat Diffusion tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

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 bouncing ball from your own measurements.

Reading this result: Heat spreads outward at a rate set by the diffusivity — each cell relaxes toward the average of its six neighbors every step.

About this simulation

The full 3D Heat Diffusion tool models a bouncing ball 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.
