Galactic nuclei are perfect laboratories for studying physical processes in the vicinity of a supermassive black hole and for exploring the impact of the massive black hole on its stellar and interstellar environment. High resolution observations of the Milky Way nucleus, which is very quiet, provide detailed and specific information that can be compared to numerical models. Our model for the dynamical evolution of a galactic nucleus takes into account the formation and evolution of binaries as well as stellar evolution. We model the tidal disruption and accretion of stars onto the central black hole by a simplified model. In this talk I will present some results from the simulation of the Galactic Centre
