We discuss the chemodynamical evolution of the Galaxy using our GRAPE-SPH code. It treats dark matter, gas, star particles and contains the physical processes of cooling, star formation, feedback from Type Ia and II supernovae (SNe Ia and II) and stellar winds, and chemical enrichment. For SNe Ia, we adopt the single degenerate scenario with the metallicity effect. We construct the detailed model of the formation and evolution of the Galaxy and compare a number of observational properties, such as age-metallicity relation, the evolutionary change in the abundance ratio, and the metallicity number distribution.
