ORB5X v1.0: a performance-portable global electromagnetic gyrokinetic PIC code in C++/Kokkos built using Agentic AI
Mohsen Sadr, Emmanuel Lanti, Alexey Mishchenko +2
ORB5X is a C++17/Kokkos AI-assisted translation of ORB5, a global electromagnetic gyrokinetic particle-in-cell code for toroidal confined plasmas. The translation preserves the mat…

Generalized mixed variable-pullback scheme with non-ideal Ohm's law for electromagnetic gyrokinetic simulations
Zhixin Lu, Guo Meng, Roman Hatzky +3
In this work, the non-ideal Ohm's law is integrated in the mixed variable-pullback scheme for the gyrokinetic particle simulations. This scheme captures the evolution of the symple…

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-…
