Abstract: β CMi is a well-known close and bright classical Be star. Its observable properties, especially the little variability of line emission, point at an exceptional stability of the circumstellar disk at least on a scale of decades, which makes β CMi an ideal laboratory for a detailed test of the viscous decretion disk (VDD) scenario currently assumed to explain the formation and evolution of Be disks. A large set of multi-wavelength and multi-technique observations is used to produce arguably the most constrained model to date. The SED has been, for the first time with a physical model, reasonably reproduced from ultraviolet up to radio wavelengths. In this contribution we present the general aspects of the model and look more closely on the diagnostic potential of the ultraviolet spectrum and the spectral shape of visual polarisation in constraining some of the central star parameters for the case of β CMi.
