Confined Lennard-Jones Two Piston System Description

The Confined Lennard-Jones Two Piston System was designed to complement the theoretical work describing the adiabatic expansion of an ideal gas using the quasi-static approximation. Users can set the number of particles N, their diameter and their initial particle kinetic energy. Slow-moving particles are color-coded as blue and fast particles are color-coded as yellow. The time evolution of temperature, pressure, and piston speed are shown in a second window. Particles in this model have unit mass and interact through contact forces. Collision times are computed analytically because particles and pistons move with constant velocity between collisions. The time evolution algorithm advances the particle and position positions from collision to collision until the requested time step is achieved. The time evolution is then pause, data is accumulated, and the screen is redrawn.
