Large Scale Structure
Large scale structure of the Universe calculated with Arepo in a gravity-only simulation (1.5 Gpc side length, 1,073,741,824 simulation particles).
Kelvin–Helmholtz instability
Snapshot of a 2d Kelvin-Helmholtz instability simulation with Arepo.
Images of examples and tests
Images of the example runs provided with Arepo. They can be easily reproduced by using the test.sh script, removing the rm commands to keep the output and replace python ${RUNDIR}/check.py ${RUNDIR} with python ${RUNDIR}/check.py ${RUNDIR} True.
wave 1d
Propagation of a small adiabatic perturbation.
shocktube 1d
Time evolution of a Riemann problem.
interacting blastwaves 1d
Interaction of two Riemann problems.
mhd shocktube 1d
Riemann problem in magnetohydrodynamics.
polytrope 1d spherical
Self-gravitating gas sphere in hydrostatic equilibrium, calculated in 1d spherical coordinates.
gresho 2d
Gresho vortex in 2d, where the rotation is balanced by a pressure gradient. Problem is supposed to be stationary.
noh 2d
Converging flow resulting in a strong shock in 2d.
yee 2d
Yee vortex problem in 2d. Similar to a Gresho vortex, only rotation and pressure profiles here are smooth.
current sheet 2d
MHD current sheet problem in 2d studying the (numerical) magnetic resistivity of the code.
noh 3d
3d version of a converging flow resulting in a strong shock.
cosmo box gravity only 3d
A cosmological volume gravity-only simulation.
cosmo box star formation 3d
A cosmological volume simulation including dark matter, gas, gas cooling and star-formation.
cosmo zoom gravity only 3d
Small version of a cosmological ‘zoom’ simulation (gravity only).
galaxy merger star formation 3d
Isolated galaxy merger simulation with dark matter, stars and gas. Includes gas cooling and star formation.
isolated galaxy collisionless 3d
Isolated galaxy (dark matter and stars, no gas) in dynamical equilibrium. Supposed to be stationary.
