Magnetic-fusion plasmas are complex self-organized systems with an extremely wide range
of spatial and temporal scales, from the electron-orbit scales (∼ 10− 11 s,∼ 10− 5 m) to the …

With ITER, the largest tokamak ever built, and the growing number of fusion energy startups
in the world, the need for numerical simulations has never been more crucial to progress …

The new code TOKAM3X simulates plasma turbulence in full torus geometry including the
open field lines of the Scrape-off Layer (SOL) and the edge closed field lines region in the …

We describe a new version of GBS, a 3D global, flux-driven plasma turbulence code to
simulate the turbulent dynamics in the tokamak scrape-off layer (SOL), superseding the code …

The proper boundary conditions at the magnetic presheath entrance for plasma fluid
turbulence models based on the drift approximation are derived, focusing on a weakly …

The transport of heat and particles in the relatively collisional edge regions of magnetically
confined plasmas is a scientifically challenging and technologically important problem …

A new open source tool for fluid simulation of multi-component plasmas is presented, based
on a flexible software design that is applicable to scientific simulations in a wide range of …

We present an energy-conserving discontinuous Galerkin scheme for the full-, the inductive
component of the parallel electric field, using a generalized Ohm's law derived directly from …

The global drift-ballooning (GDB) code is developed to study tokamak edge low frequency
turbulence and transport, and their relationship to global profile evolution. The code employs …

The purpose of the present paper is to provide an overview of Asymptotic-Preserving
methods for multiscale plasma simulations by addressing three singular perturbation …
