🧊 Lennard-Jones Piston Cell: Gas, Liquid and Solid by Molecular Dynamics

500 argon-like atoms in a heated, squeezable cell with a pressure gauge: live Lennard-Jones molecular dynamics shows gas, liquid, droplet and crystal states, wall and virial pressure, g(r), and checks against the second virial coefficient and the fcc lattice energy.
