Achievable Efficiency of Numerical Methods for Simulations of Solar Surface Convection
Hannes Grimm-Strele, Friedrich Kupka, Herbert J. Muthsam
We investigate the achievable efficiency of both the time and the space discretisation methods used in Antares for mixed parabolic-hyperbolic problems. We show that the fifth order…
Curvilinear Grids for WENO Methods in Astrophysical Simulations
Hannes Grimm-Strele, Friedrich Kupka, Herbert J. Muthsam
We investigate the applicability of curvilinear grids in the context of astrophysical simulations and WENO schemes. With the non-smooth mapping functions from Calhoun et al. (2008)…
A Low Mach Number Solver: Enhancing Applicability
Natalie Happenhofer, Hannes Grimm-Strele, Friedrich Kupka +2
In astrophysics and meteorology there exist numerous situations where flows exhibit small velocities compared to the sound speed. To overcome the stringent timestep restrictions po…
