Understanding the accretion process and linking theoretical models with observations is among the major open questions in star formation. The dynamical evolution of accretion shocks in young stars depends strongly on the local magnetic field strength and configuration, as well as on the radiative transfer effects responsible for the energy losses.
I will present 3D MHD simulations of an accretion stream impacting onto the chromosphere of a young star, assuming a uniform background magnetic field and optically thin radiation losses. I will then discuss the observational relevance of the post-shock structure for different values of the magnetic field.
