  The performance of the ALBA light source will be strongly determined by the quality of the bending magnet. In the ALBA case, most of the vertical focusing takes place in the combined function bending magnet, and the contribution of the edge focusing is required to obtain a stable working point. Experience from other modern light sources using combined function magnets (CLS, ASP, Spear-III) shows that the usual hard model is not sufficient for an accurate modelling of the machine. In this paper, we review the methods to model the effect of the bending magnet, including fringe fields, and how to obtain a good model from the 3D magnetic model.
