Welcome to theĀ SciDAC-4 Center for
High-Fidelity Boundary Simulation
(Project PI: Choong-Seock Chang, PPPL)
The HBPS SciDAC Partnership will develop advanced fusion simulation
codes based upon first-principles physical models to provide insight into edge plasma
physics in magnetic fusion devices. Collaborations with the SciDAC Institutes
will ensure reliable and efficient solution of validated models on
extreme-scale, high-performance computers. For more information on the center click here.
This figure shows an electrostatic potential perturbation
from a petascale simulation of full-function gyrokinetic
ion temperature gradient turbulence in realistic global
DIII-D geometry. The magnetic separatrix surface
is highlighted in the edge region.
This movie explains the physics of the self-generated bootstrap current in the narrow H-mode edge pedestal in tokamak plasmas, especially the important role of trapped particles (published in Physics of Plasmas, 2016).
