Kinetic modeling of neutral transport for a continuum gyrokinetic code
T. N. Bernard, F. D. Halpern, M. Francisquez +6
We present the first-of-its-kind coupling of a continuum full-f gyrokinetic turbulence model with a 6D continuum model for kinetic neutrals, carried out using the Gkeyll code. Our…
Mapped discontinuous Galerkin interpolations and sheared boundary conditions
Manaure Francisquez, Noah R. Mandell, Ammar Hakim +1
Translations or, more generally, coordinate transformations of scalar fields arise in several applications, such as weather, accretion disk and magnetized plasma turbulence modelin…
Magnetic Fluctuations in Gyrokinetic Simulations of Tokamak Scrape-Off Layer Turbulence
Noah Mandell
Understanding turbulent transport physics in the tokamak edge and scrape-off layer (SOL) is critical to developing a successful fusion reactor. The dynamics in these regions plays…
Conservative discontinuous Galerkin scheme of a gyro-averaged Dougherty collision operator
Manaure Francisquez, Tess N. Bernard, Noah R. Mandell +2
A conservative discontinuous Galerkin scheme for a nonlinear Dougherty collision operator in full-f long-wavelength gyrokinetics is presented. Analytically this model operator has…
Electromagnetic full- gyrokinetics in the tokamak edge with discontinuous Galerkin methods
N. R. Mandell, A. Hakim, G. W. Hammett +1
We present an energy-conserving discontinuous Galerkin scheme for the full- electromagnetic gyrokinetic system in the long-wavelength limit. We use the symplectic formulation an…
The Parallel Boundary Condition for Turbulence Simulations in Low Magnetic Shear Devices
Mike F. Martin, Matt Landreman, Pavlos Xanthopoulos +2
Flux tube simulations of plasma turbulence in stellarators and tokamaks typically employ coordinates which are aligned with the magnetic field lines. Anisotropic turbulent fluctuat…
