Recent yearVolker Springel-043bs have seen impressive progress towards hydrodynamic cosmological simulations of galaxy formation that try to account for much of the relevant physics in a realistic fashion. At the same time, numerical uncertainties and scaling limitations in the available simulation codes have been recognized as important challenges. I will review the state of the field in this area, highlighting a number of recent results obtained with large SPH-based and mesh-based simulations. In particular, I will discuss simulations that aim to produce disc galaxies similar to the Milky Way, consistently embedded in the cosmological framework of LCDM.
