Energy-Conserving Discontinuous Galerkin Methods for Vlasov Systems
Prof. Xing-Hui Zhong
Zhejiang University

We propose energy-conserving numerical schemes for the Vlasov-type  systems. Those equations are fundamental models in the simulation of plasma  physics. The total energy is an important physical quantity that is conserved  by those models. Our methods are the first Eulerian solver that can  preserve fully discrete total energy conservation. The main features of our  methods include energy-conservative temporal and spatial discretization. In particular, an energy-conserving operator splitting is proposed to  enable efficient calculation of fully implicit methods. We validate our  schemes by rigorous derivations and benchmark numerical examples.
