We present our recently developed 3-dimensional chemodynamical code for galaxy evolution .
It follows the evolution of all components of a galaxy such as dark matter , stars , molecular clouds and diffuse interstellar matter ( ISM ) .
Dark matter and stars are treated as collisionless N -body systems .
The ISM is numerically described by a smoothed particle hydrodynamics ( SPH ) approach for the diffuse ( hot ) gas and a sticky particle scheme for the ( cool ) molecular clouds .
Additionally , the galactic components are coupled by several phase transitions like star formation , stellar death or condensation and evaporation processes within the ISM .
As an example here we present the dynamical , chemical and photometric evolution of a star forming dwarf galaxy with a total baryonic mass of 2 \times 10 ^ { 9 } { M } _ { \odot } .
