Abstract

The ANTARES code (A Numerical Tool for Astrophysical RESearch) is designed for doing 1D, 2D and 3D stellar (radiation-, magneto-) hydrodynamics with realistic microphysics, applying various high-resolution numerical schemes, optionally local grid refinement and works with rectilinear or spherical coordinates. – We present results on turbulent solar granulation flows which have been done in 2D and 3D and comment on our simulations of the pulsation-convection interaction in Cepheid variables, presently 2D.
