We study the effect of different star formation regimes on the dynamical and chemical evolution of the Dwarf Galaxy IZw18. To do that, we make use of a 2-D hydrocode coupled with detailed chemical yields originating from SNeII, SNeIa and low- and intermediate-mass stars. The results of our simulations are that IZw18 is a pretty young galaxy (we do not need to invoke stars older than 300 Myr in order to reproduce the chemical properties of this object) and the last burst of star formation occurred at most 15 Myr ago.
