Cim:"Multi-Phase Chemo-Dynamical SPH modeling of galaxy formation
    and evolution"

Kivonat:
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 x 10^9 Mo.
