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…
Total-Variation-Diminishing Implicit-Explicit Runge-Kutta Methods for the Simulation of Double-Diffusive Convection in Astrophysics
Friedrich Kupka, Natalie Happenhofer, Inmaculada Higueras +1
We put forward the use of total-variation-diminishing (or more generally, strong stability preserving) implicit-explicit Runge-Kutta methods for the time integration of the equatio…
Simulations of stellar convection, pulsation and semiconvection
Herbert J. Muthsam, Friedrich Kupka, Eva Mundprecht +3
We report on modelling in stellar astrophysics with the ANTARES code. First, we describe properties of turbulence in solar granulation as seen in high-resolution calculations. Then…
