Abstract

A system of orientationally persistent, spherical active particles, without thermal or noise effects, that wait when they collide, but can otherwise freely move through each other, is simulated and investigated for clustering behaviour. It is explained how the event-based simulation of this system works. Then, a simple theoretical model is built attempting to describe the system and find conditions for clustering. The simulations show a clustering behaviour that depends on how the waiting time of the particles is determined.
