The GRILLIX code is presented with which plasma turbulence/transport in various
geometries can be simulated in 3D. The distinguishing feature of the code is that it is based …

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

A review of recent advances in simulations of turbulent filaments with relevance to
stellarators is presented. Progress in performing global edge turbulence simulations is …

Predictions of plasma parameters in the edge and scrape-off layer of tokamaks is difficult
since most modern tokamaks have a divertor and the associated separatrix causes the …

Here we present first results simulating plasma filaments in non-axisymmetric geometries,
using a fluid turbulence extension of the BOUT++ framework. This is made possible by the …

Isothermal fluid turbulence simulations have been performed in the edge and scrape-off
layer (SOL) of an analytic stellarator configuration with an island divertor, thereby providing …

Understanding turbulent transport physics in the tokamak edge and scrape-off layer (SOL) is
critical to developing a successful fusion reactor. The dynamics in these regions plays a key …

In this work, we address the question of the influence of magnetic islands on the
perpendicular transport due to steady-state ITG turbulence on the energy transport time …

We present and discuss three discontinuous Galerkin (dG) discretizations for the anisotropic
heat conduction equation on non-aligned cylindrical grids. Our non-aligned scheme relies …

The flux-coordinate independent approach (FCI) offers a promising solution to deal with a
separatrix and X-point (s) in diverted tokamaks. Whereas the discretisation of perpendicular …
