The energy flow equation

R. Vichnevetsky

Mathematics and Computers in Simulation (MATCOM), 1984, vol. 26, issue 2, 93-101

Abstract: An equation which describes the flow of energy in energy conservative semi- and full discretizations of hyperbolic equations is derived. While the form of this equation for semi-discretizations verfies known principles of group velocity and wave propagation in periodic structures, its form and strict applicability to discrete-space—discrete-time systems such as those resulting from the full discretization of hyperbolic equations are new results.
