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-…
Full and gyrokinetic particle simulations of Alfvén waves and energetic particle physics
Zhixin Lu, Guo Meng, Roman Hatzky +2
In this work, we focus on the development of the particle-in-cell scheme and the application to the studies of Alfvén waves and energetic particle physics in tokamak plasmas. The $…
ORB5: a global electromagnetic gyrokinetic code using the PIC approach in toroidal geometry
E. Lanti, N. Ohana, N. Tronko +20
This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code…
Pullback scheme implementation in ORB5
Alexey Mishchenko, Alberto Bottino, Alessandro Biancalani +9
The pullback scheme is implemented in the global gyrokinetic particle-in-cell code ORB5 [S. Jolliet et al, Comp. Phys. Comm., 177, 409 (2007)] to mitigate the cancellation problem…
