A Maxwell-Lorentz solver for self-consistent particle-field simulations on unstructured grids

The conceptual and algorithmic framework solving numerically the time-dependent Maxwell-Lorentz equations on an unstructured mesh in two and three space dimensions is presented. Beyond a brief review of the applied charged particle handling based on advanced particle-in-cell techniques, a modern finite-volume scheme for the numerical approximation of the three-dimensional, time-dependent Maxwell equations is introduced using unstructured grid arrangements. Furthermore, the algorithmic realization of the resulting numerical schemes is described in great detail. Apart from this, simulation results for typical benchmark problems computed with the particle treatment and Maxwell solver are presented, demonstrating the quality and properties as well as the relevance and reliability of the applied numerical methods.
