A Multi-Phase Chemo-Dynamical SPH code for galaxy evolution. Testing the code

In this paper we present some test results of our newly developed Multi-Phase Chemo-Dynamical Smoothed Particle Hydrodynamics (MP-CD-SPH) code for galaxy evolution. At first, we present a test of the 'pure' hydro SPH part of the code. Then we describe and test the multi-phase description of the gaseous components of the interstellar matter. In this second part we also compare our condensation and evaporation description with the results of a previous 2d multi-phase hydrodynamic mesh code.
