The Confined Lennard-Jones System is an idealized statistical mechanics model that simulates a two-dimensional system of particles confined to a box with a constant temperature thermal reservoir at one end and a movable piston at the other. Particles in this model have unit mass and interact... Platforms: Mac

The Lennard-Jones PVT System simulates a two-dimensional system of particles confined between a thermal reservoir and a piston. This computer model is designed to study the equation of state for particles interacting via a simple but realistic molecular potential that has a weak long-range... Platforms: Mac

As anyone who has tried it will know, writing particle effects for games is often a long and arduous process, especially if said effects need to render in real time and interact with the environment. PyIgnition is a particle effects engine written for use in Pygame which sets out to make the... Platforms: Mac
