Geometric numerical discretization of a quasineutral hybrid model of drift-kinetic electrons and fully kinetic ions
Nishant Narechania, Guo Meng, Emil Poulsen +1
We extend the geometric electromagnetic particle-in-cell (PIC) framework, GEMPICX, to solve the quasineutral hybrid Vlasov-Maxwell equations with drift-kinetic electrons and fully…
On the Poisson brackets of hybrid plasma models with kinetic ions and massless electrons
Yingzhe Li, Philip J. Morrison, Stefan Possanner +1
We investigate the conditions under which the Jacobi identity holds for a class of recently introduced anti-symmetric brackets for the hybrid plasma models with kinetic ions and ma…
A geometric Particle-In-Cell discretization of the drift-kinetic and fully kinetic Vlasov-Maxwell equations
Guo Meng, Katharina Kormann, Emil Poulsen +1
In this paper, we extend the geometric Particle in Cell framework on dual grids to a gauge-free drift-kinetic Vlasov--Maxwell model and its coupling with the fully kinetic model. W…
Semi-Lagrangian methods for a plasma hybrid model with multi-species kinetic ions and massless electrons
Yingzhe Li, Philip J. Morrison, Eric Sonnendrücker
The semi-Lagrangian methods with the improved number of one-dimensional advections are proposed for a plasma hybrid model with kinetic ions and mass-less electrons. Two subsystems…
Piecewise Field-Aligned Finite Element Method for Multi-Mode Nonlinear Particle Simulations in tokamak plasmas
Zhixin Lu, Guo Meng, Eric Sonnendrücker +5
This paper presents a novel approach for simulating plasma instabilities in tokamak plasmas using the piecewise field-aligned finite element method in combination with the particle…
Gyrokinetic Electromagnetic Particle Simulations in Triangular Meshes with C1 Finite Elements
Zhixin Lu, Guo Meng, Roman Hatzky +6
The triangular mesh-based gyrokinetic scheme enables comprehensive axis-to-edge studies across the entire plasma volume. Our approach employs triangular finite elements with first-…
