Molecular Dynamics for a polymer chain

Built for first responders planning or training for real incidents. Run fast what-if scenarios for response planning and training — no software to install in the field. Simulate a polymer chain live below — adjust the inputs and watch it respond, right in your browser.

Governing equation

V (r) = 4 ε [(\frac{σ}{r})^{12} - (\frac{σ}{r})^{6}], F = - \frac{d V}{d r} = m \overset{r}{¨} (N = 120, T = 0.0)

Reading this result: Near a target of 120, thermal energy rivals the Lennard-Jones well depth, so the 120-atom lattice loses its order and begins to flow — melting.
