Particular care was taken to keep the C++11 codebase simple, concise, and approachable. GMRES is used as a field solver and during the Newton–Krylov iteration of the particle pusher. Drifting Maxwellian problem setups are available while more complex simulations can be implemented easily. Several test runs are described and the code’s numerical and computational performance is examined. Weak scaling on the SuperMUC system is discussed and found suitable for large-scale production runsenNewton–KrylovGMRESparticle in cellimplicit momentrelativistic implicit momentparticle meshArticle
