The chemical and photometric evolution of star forming disk galaxies is investigated. Numerical simulations of the complex gasdynamical flows are based on our own coding of the Chemo - Dynamical Smoothed Particle Hydrodynamical (CD - SPH) approach, which incorporates the effects of star formation. The presented model describes well the time evolution of the basic dynamical, chemical and photometric parameters of a disk galaxy similar to the Milky Way. The metallicity, luminosity and colors obtained are typical for such disk galaxies. During the calculations we made an extended test of the proposed SF criteria. We find that the obtained results with different "gas" and "star" particle numbers are not only qualitatively but also quantitatively similar.
