This paper presents the current state of the global gyrokinetic code Orb 5 as an update of the
previous reference (Jolliet et al., 2007). The Orb 5 code solves the electromagnetic Vlasov …

Aiming to fill a corresponding lack of sophisticated test cases for global electromagnetic
gyrokinetic codes, a new hierarchical benchmark is proposed. Starting from established test …

We present the first simulations of a reduced magnetized plasma model that incorporates
both arbitrary wavelength polarization and non-Oberbeck–Boussinesq effects. Significant …

We present a scheme that spatially couples two gyrokinetic codes using first-principles.
Coupled equations are presented and a necessary and sufficient condition for ensuring …

In this work, we highlight an issue that may reduce the accuracy of many local nonlinear
gyrokinetic simulations–turbulent self-interaction through the parallel boundary condition …

A detailed cross-verification between two global gyrokinetic codes, the core continuum code
GENE and the edge particle-in-cell code XGC, for the linear and nonlinear simulations of ion …

Self-interaction is the process by which a microinstability eigenmode that is extended along
the direction parallel to the magnetic field interacts non-linearly with itself. This effect is …

We propose a solution to the long-standing short wavelength polarization closure shortfall of
full-F gyro-fluid models. This is achieved by first finding an appropriate quadratic form of the …

The work reported in this paper addresses two aspects. In the first part, numerical
simulations are conducted to examine the impact of magnetic equilibrium shaping …

Non-adiabatic electron response leads to significant changes in ion temperature gradient
(ITG) eigenmodes, leading, in particular, to fine-structures that are significantly extended …
