The Landau Collision Integral in the Particle Basis in the PETSc Library
Joseph Pusztay, Filippo Zonta, Matt Knepley +1
The Landau collision integral is often considered the gold standard in the context of kinetic plasma simulation due to its conservative properties, despite challenges involved in i…
Multispecies structure-preserving particle discretization of the Landau collision operator
Filippo Zonta, Joseph V. Pusztay, Eero Hirvijoki
This paper proposes a novel numerical integrator for modeling multispecies Coulomb collisions in kinetic plasmas. The proposed scheme provides an energy-, momentum-, and positivity…
Subcycling of particle orbits in variational, geometric electromagnetic particle-in-cell methods
Eero Hirvijoki, Katharina Kormann, Filippo Zonta
This paper investigates subcycling of particle orbits in variational, geometric particle-in-cell methods addressing the Vlasov--Maxwell system in magnetized plasmas. The purpose of…
