✦ Synopsis

An efficient algorithm for the calculation of short-range Coulomb energies is examined. The algorithm uses a boxing scheme and a prescreening for negligible integrals to evaluate the short-range Coulomb energy via computational work that scales only linearly with the size of the system.

A P3M (particle-particle, particle-mesh) algorithm to compute the gravitational force on a set of particles is described. The gravitational force is computed using fast Fourier transforms. This leads to an incorrect force when the distance between two particles is of the order of a grid cell. This i
