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.
