How do I simulate a footbridge?

Open this page and use the live Meshing + BCs 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 footbridge from your own measurements.

Governing equation

\nabla^{2} u = 0 \Rightarrow u_{i, j} = \frac{1}{4} (u_{i - 1, j} + u_{i + 1, j} + u_{i, j - 1} + u_{i, j + 1}), 100 \times 100 grid, r = 0.00 e + 0

Reading this result: At steady state ∇²u=0 means every interior cell equals the average of its four neighbors, so heat spreads smoothly between the fixed hot and cold edges.

About this simulation

The full Meshing + BCs tool models a footbridge 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.
