Simulating hard rigid bodies
Hard rigid bodies are a reference system to understand the properties of molecular fluids, especially regarding the steric effects. Nevertheless, apart the case of hard spheres systems, there are no general recipes for Monte Carlo or Event Driven Molecular Dynamics simulations. We introduce a new algorithm to calculate the distance between two convex surfaces. Building up on such result, we introduce a new event-driven (ED) molecular dynamics algorithm for simulating systems of hard convex bodies. In order to optimize collision detection between elongated objects, we introduce a new nearest-neighbour list based on oriented bounding parallelepipeds. We show in detail algorithm's efficiency simulating a system of hard ellipsoids of revolution (HE) and discuss the possible applications of our new techniques in various scientific and technological fields.
