Abstract
For the Particle-In-Cell (PIC) method which is used to simulate non-neutral
plasma the charge conservation is violated. To solve this problem several approaches have
been suggested. In this paper we shall investigate the hyperbolic divergence cleaning
method. It has been proposed in two different manners, one enforcing only Gauss’ law
and another considering both Gauss’ law and the magnetic monopole divergence constraint.
We shall investigate the differences between the two approaches with numerical
simulations of a quasi 2D diode with the PIC method and a pure Maxwell equations example
satisfying the charge conservation in its initial conditions. We use a discontinuous
Galerkin FEM-type space discretization method to solve the Maxwell equations. The
results of the numerical investigations are presented and the advantages or disadvantages
of both approaches w.r.t. performance and quality are discussed.
