Here we present details of an operator-split, implicit–explicit numerical scheme for the
solution of the gyrokinetic-Poisson system of equations in the local limit. This scheme has …

In this paper, a hybrid Hermite weighted essentially non-oscillatory scheme is proposed for
nonlinear degenerate parabolic equations which may contain discontinuity in the solution …

The first continuum gyrokinetic calculations of electrostatic ion scale turbulence are
presented for the case of a diverted tokamak geometry. The simulation model solves the …

We describe a new spatial discretization of a continuum gyrokinetic Vlasov model in
axisymmetric tokamak edge plasma geometries. The geometries are represented using a …

Eulerian kinetic calculations are presented for the axisymmetric cross‐separatrix plasma
transport at the edge of a tokamak. The simulations are performed with a high‐order finite …

In this paper, a sixth-order Hermite weighted essentially non-oscillatory (HWENO) scheme
based on finite difference framework is proposed for one-and two-dimensional nonlinear …

We report on the development and implementation of a hybrid kinetic ion–fluid electron
model for electromagnetic COGENT simulations of edge plasmas. COGENT is a finite …

The high confinement mode, called H-mode, which is the foreseen plasma configuration for
high performance operation of the ITER tokamak, exhibits strong pressure gradients and …

Two schemes for coupling gyrokinetic simulations of microturbulence in tokamaks are
proposed. The first scheme is based on an additive Schwarz domain decomposition. We …

In this paper, we develop a novel reconstruction-based finite difference weighted essentially
non-oscillatory (WENO) scheme for nonlinear degenerate parabolic equations that may …
