An energy concerving modification of numerical methods for the integration of equations of motion

Robert A. Labudde and Donald Greenspan

International Journal of Mathematics and Mathematical Sciences, 1987, vol. 10, 1-7

Abstract:

In the integration of the equations of motion of a system of particles, conventional numerical methods generate an error in the total energy of the same order as the truncation error. A simple modification of these methods is described, which results in exact conservation of the energy.
