Detailed Description

A cell-based method for calculating forces.

Author:

Aaron Keys

Using a BruteForce scheme, we waste many CPU cycles calculating distances between pairs of particles that are clearly outside the interaction range, especially if the system is large. Optimally, we would only calculate the distances we need (i.e., the distances lying within a spherical shell given by the interaction range for each particle). We approximate this shell by gridding the system into discrete boxes (cells) and only calculate distances between particles in neighboring cells. This method scales with N, where N is the number of particles in the simulation.
