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-…
Energetic particles transport in constants of motion space due to collisions in tokamak plasmas
Guo Meng, Philipp Lauber, Zhixin Lu +2
The spatio-temporal evolution of the energetic particles in the transport time scale in tokamak plasmas is a key issue of the plasmas confinement, especially in burning plasmas. In…
High-order stochastic integration schemes for the Rosenbluth-Trubnikov collision operator in particle simulations
Zhixin Lu, Guo Meng, Tomasz Tyranowski +1
In this study, we consider a numerical implementation of the nonlinear Rosenbluth-Trubnikov collision operator for particle simulations in plasma physics in the framework of the fi…
