The authors describe a two-dimensional hydrodynamical code developed for the study of accretion flows with angular momentum. It is written for spherical polar coordinates with origin in the accreting object and it assumes axial symmetry. Advection is performed with an explicit flux-corrected-transport algorithm. Viscous diffusion is calculated implicitly with a standard ADI method and viscous dissipation can be incorporated if desired. A variety of boundary conditions are allowed, covering most cases of astrophysical interest. Preliminary results on the modelling of the boundary layer between a Keplerian accretion disc and a rigid non-rotating star are presented. The authors also display their first results on the evolution of a thick accretion disc or torus due to a large kinematic viscosity.
