We present a numerical method to combine radiation processes for diffuse gaseous nebulae with numerical gasdynamic methods. The method encompasses detailed calculations of the ionization, heating, and cooling processes. We have constructed two codes based on different gasdynamic numerical methods: FCT/LCD and a Roe Solver. We apply the two new radiation-gasdynamics codes to the interacting winds model for the formation of planetary nebulae (PNe) and compare the results to the non-radiative results.
