ABSTRACT:
This invention provides a computing device which calculates the total energy and total pairwise, central forces between selected pairs of interacting particles within a system. The device comprises (a) a means for generating both (i) a retrievable identifier for the spatial coordinates (x, y, z) of a particle i and (ii) retrievable identifiers of the type of pairwise, central interaction between i and a second particle j; (b) a means for determining r.sup.2, the square of the radius vector between i and j; (c) a means for determining r, the square root of r.sup.2 ; (d) a means for calculating energy and force/r values for each ij pair; (e) means for determining the force on each particle; and (f) means for accumulating energy and force/r values for each ij particle pair.
