Abstract
A particle simulation device comprises: a position information acquisition unit that acquires position information for the particles; a pair setting unit that selects pairs of particles and sets a pair number, on the basis of the position information; a reference information generation unit that generates a matrix from the pair numbers and the particle numbers, and generates reference information for referencing the pair numbers from the particle numbers on the basis of a matrix in which the order of the rows of the matrix are sorted on the basis of the particle numbers; a sum calculation unit that calculates a sum of interaction forces for each particle on the basis of the reference information; and a particle information calculation unit that calculates the position and velocity of the particles on the basis of the sum of interaction forces.
