Advances in computing capabilities have made it possible to perform multi-dimensional radiation MHD simulations with a realistic description of the physics in the photosphere. In the chromosphere non-LTE becomes important and the choice is between realistic physics in one dimension and approximations to the non-local radiation in multi-dimensions. We will here discuss such simulations from a methodological vantage point. We will discuss how we can make such simulations to study how waves are excited in the solar convection zone, how they propagate through the chromosphere and transition region and undergo mode conversion, refraction and reflection in various magnetic field topologies. We will also discuss the limitations of observational diagnostics with respect to wide response functions, non-locality and non-equilibrium effects.
