Geometric Integration Of The Valsov-Maxwell System With A Variational Particle-in-cell Scheme
Authors: J. Squire, H. Qin and W.M. Tang
Abstract:
A fully variational, unstructured, electromagnetic particle-in-cell integrator is developed for integration
of the Vlasov-Maxwell equations. Using the formalism of Discrete Exterior Calculus [1], the field solver,
interpolation scheme and particle advance algorithm are derived through minimization of a single discrete
field theory action. As a consequence of ensuring that the action is invariant under discrete electromagnetic
gauge transformations, the integrator exactly conserves Gauss's law.
