Single Gaussian Process Method for Arbitrary Tokamak Regimes with a Statistical Analysis
Jarrod Leddy, Sandeep Madireddy, Eric Howell +1
Gaussian Process Regression (GPR) is a Bayesian method for inferring profiles based on input data. The technique is increasing in popularity in the fusion community due to its many…
Growing Neoclassical Tearing Modes Seeded via Transient-Induced-Multimode Interactions
E. C. Howell, J. R. King, J. D. Callen +3
Nonlinear extended MHD simulations demonstrating seeding of neoclassical tearing modes (NTMs) via MHD-transient-induced multimode interactions are presented. Simulations of NTMs ar…
Toward Performance-Portable PETSc for GPU-based Exascale Systems
Richard Tran Mills, Mark F. Adams, Satish Balay +11
The Portable Extensible Toolkit for Scientific computation (PETSc) library delivers scalable solvers for nonlinear time-dependent differential and algebraic equations and for numer…
The Three Quasistatic Limits of the Maxwell Equations
Scott E. Kruger
It is shown that the Galilean limit (V << c, or L/T <<c)) of the Maxwell equations admits three different limits: the magneto-quasi-static, electro-quasi-static, and electromagneti…
MHD modeling of a DIII-D low-torque QH-mode discharge and comparison to observations
J. R. King, S. E. Kruger, K. H. Burrell +6
Extended-MHD modeling of DIII-D tokamak [J. L. Luxon, Nucl. Fusion 42, 614 (2002)] quiescent H-mode (QH-mode) discharges with nonlinear NIMROD [C. R. Sovinec et al., J. Comput. Phy…
Effect of Scrape-Off-Layer Current on Reconstructed Tokamak Equilibrium
J. R. King, S. E. Kruger, R. J. Groebner +4
Methods are described that extend fields from reconstructed equilibria to include scrape-off-layer current through extrapolated parametrized and experimental fits. The extrapolatio…
