We present some preliminary results obtained with a new galactic chemodynamical tool under development. In the framework of non-instantaneous recycling approach, we follow the interactions due to star formation and feedback processes. One of the main original features of our code is that we record the abundance evolution of several chemical elements. This allows us to build cooling functions dependent on the real abundances of individual elements. We illustrate the need for such metal-dependent cooling functions using a toy model made of a star cluster embedded in a two-phase gas cloud. Our results suggest that computing cooling rates according to individual abundances of chemical elements can influence the star formation rate.
