A Conservative Discontinuous Galerkin Algorithm for Particle Kinetics on Smooth Manifolds
Grant Johnson, Ammar Hakim, James Juno
A novel, conservative discontinuous Galerkin algorithm is presented for particle kinetics on manifolds. The motion of particles on the manifold is represented using using both cano…

Modeling of Relativistic Plasmas with a Conservative Discontinuous Galerkin Method
James Juno, Grant Johnson, Alexander Philippov +3
We present a new method for solving the relativistic Vlasov--Maxwell system of equations, applicable to a wide range of extreme high-energy-density astrophysical and laboratory env…

Discontinuous Galerkin Representation of the Maxwell-Jüttner Distribution
Grant Johnson, Ammar Hakim, James Juno
Kinetic simulations of relativistic gases and plasmas are critical for understanding diverse astrophysical and terrestrial systems, but the accurate construction of the relativisti…
