Minisymposium Presentation

The GEMPICX code is a geometric particle in cell solver for plasma physics models. It can handle both electrostatic and fully magnetic simulations. The code is able to leverage modern (including GPU-based) high performance computing systems by utilizing the AMREX framework for block structured adaptive mesh refinement. In this talk, we are going to present recent developments to add relativistic effects to the GEMPICX code. We start with a Hamiltonian splitting and further decompose the particle part into the gyromotion and the free streaming part, which allows us to treat both parts exactly.
