Since the aim is to have more than a thousand of realisations, each individual run is simplified, with a small number of particules (24 000), but following the chemodynamical evolution, with star formation and feedback. We illustrate in this short report some preliminary results.2 pages, 2 figures, contribution in Scientific Highlights, SF2A-2003, to be published by EDP-SciencesAstrophysicstext
