Tracking of high intensity effects for few turns of a circular accelerator is at reach of present computational capabilities. The situation is very different when the prediction of beam behaviour is extended to hundred of thousands of turns, where special approaches for the control of computer artifact are necessary sometimes to the expense of a complete physical modeling. The identification of the key physical ingredients helps to the development of computer algorithms capable of treating the long term tracking. In this talk it is presented the actual state of simulations for long term tracking of high intensity bunches of the SIS100 addressing the self consistent treatment of beam loss. A more realistic modeling of the incoherent effect of electron cloud is addressed as well.
