In this contribution we present the simulations of the experiment made in the SIS18 synchrotron on the effect of the space charge in a bunched beam stored for one second. To the simulations a discussion of the underlying dominant effect (trapping or scattering?) is included. A discussion on the consequences of this beam dynamic regime on the SIS100 is presented, open issues and future (experimental and numerical) studies are outlined.
