Galactic chemical evolution (GCE) describes how elements are distributed within the interstellar medium (ISM) of the galaxy through catastrophic events such as supernovae (SNe). We use various homogeneous and inhomogeneous models to simulate the environment of reactions such that they match observations of the known universe. Presented, is a new inhomogeneous model based on Argast et al. (2002) where we simulate a three dimensional box from which galaxies evolve through various SNe and enrich the system. We show several preliminary results including the dwarf galaxy Draco, where we compare observations with new metallicity gradients. Along with this, we show the star formation rate (SFR), infall time and the ratio of SNII and SNIa. Finally, we explore future prospects with this new inhomogeneous model and examine further uses through future development.
