A new N-body sticky-particles computer code for spiral galaxies is presented. The substantial improvement over existing models is the scheme for the bi-directional mass exchange between gas and stars: the cosumption of the former by star formation is taken into account by locking aq fraction of gas in newly created stars while the mass-loss from stars via stellar winds and supernova explosions is implemented as time dependent over the Hubble time.
