The chemical evolution of galaxies is the result of the joint action of several physical processes as mergers, gas inflows, supernova feedback and AGN activity among others (e.g. Larson 1974, Croton et al. 2006).  And, although it is not easy to disentangle the effect of each individual process, the analysis of the chemical abundances of galaxies may provide important clues on the evolutionary histories of these systems. In this work we study the evolution of the luminosity-metallicity  relation and the stellar mass-metallicity relation by performing chemo-dynamical simulations in a cosmological framework with the aim at understanding both relations in a hierarchical scenario.
