  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.
