Gyrokinetic equilibria of high temperature superconducting magnetic mirrors
Maxwell H. Rosen, Manaure Francisquez, James Juno +2
High-temperature superconducting (HTS) magnets and other advances have led to renewed interest in magnetic mirrors for fusion energy. The non-Maxwellian nature of mirror plasmas ne…
An explicit multiscale pseudo orbit-averaging time integration algorithm
Maxwell H. Rosen, Manaure Francisquez, Gregory W. Hammett
We present an explicit multiscale algorithm for solving differential equations for problems with high-frequency modes that can be averaged over by separating and scaling the fast a…
High-throughput full-f gyrokinetics of the tokamak boundary
A. C. D. Hoffmann, M. Francisquez, T. N. Bernard +2
Full-f global gyrokinetic simulations of the plasma boundary have until now required heroic computational efforts and case-by-case expert intervention, precluding systematic parame…
Towards fully predictive gyrokinetic full-f simulations: validation and triangularity studies in TCV
A. C. D. Hoffmann, T. N. Bernard, M. Francisquez +6
Designing economical magnetic confinement fusion power plants motivates computational tools that can estimate plasma behavior from engineering parameters without direct reliance on…
Super Time Stepping Methods for Diffusion using Discontinuous-Galerkin Spatial Discretizations
Mustafa Aggul, Manaure Francisquez, Daniel R. Reynolds +1
Super-time-stepping (STS) methods provide an attractive approach for enabling explicit time integration of parabolic operators, particularly in large-scale, higher-dimensional kine…
Conservative velocity mappings for discontinuous Galerkin kinetics
Manaure Francisquez, Petr Cagas, Akash Shukla +2
Continuum computational kinetic plasma models evolve the distribution function of a plasma species on a phase-space grid over time. In many problems of interest the distribut…
