Reproducibility, accuracy and performance of the Feltor code and library on parallel computer architectures
Matthias Wiesenberger, Lukas Einkemmer, Markus Held +3
Feltor is a modular and free scientific software package. It allows developing platform independent code that runs on a variety of parallel computer architectures ranging from lapt…
Streamline integration as a method for structured grid generation in X-point geometry
M. Wiesenberger, M. Held, L. Einkemmer +1
We investigate structured grids aligned to the contours of a two-dimensional flux-function with an X-point (saddle point). Our theoretical analysis finds that orthogonal grids exis…
A conservative discontinuous Galerkin scheme for the 2D incompressible Navier--Stokes equations
Lukas Einkemmer, Matthias Wiesenberger
In this paper we consider a conservative discretization of the two-dimensional incompressible Navier--Stokes equations. We propose an extension of Arakawa's classical finite differ…
