I will present a study of the most important physical processes that are readily available in the evolution of a spherical cluster, like self-gravity, two-body relaxation, the interaction with a central black hole and the role of a mass spectrum using an anisotropic gaseous model. This method solves numerically moment equations of the full Fokker-Planck equation, with Boltzmann-Vlasov and collisional terms. I study the growth of the central BH due to star accretion at its tidal radius and the feedback of this process on to the core collapse as well as the post-collapse evolution of the surrounding stellar cluster in a self-consistent manner.
