Our Sun is a single star, which is somewhat of an exception in the Universe as most stars are found in binary and multiple systems. For a wide range of initial conditions at stellar birth, the two stars in a binary will interact by exchanging mass, exploding, or merging to a single object. Computer simulations of binary systems are indispensable in revealing the fundamental physical processes governing the binary's structure and evolution, yet they are complicated by a lack of any useful symmetry. In this talk I will review results of radiation / magneto-hydrodynamical simulations of a common envelope evolution phase studied with the help of ERC StG and describe plans for a new set of simulations with discontinuous Galerkin method to be done with the support of ERC CoG.
