WebFor example, starting all your particles at the same spot is a bad idea. The Lennard-Jones potential has a repulsive core, so your system will start with effectively infinite potential energy. Because you are working in the micro-canonical ensemble, energy is conserved, so the kinetic energy will explode and the simulation will be unstable.
