Model atmospheres calculated with a modified version of the PHOENIX stellar atmospheric code which includes elemental stratifications will be presented. The stratifications of the various elements included in this code are obtained via the radiative diffusion process and the atmospheric structure is simultaneously calculated taking into account the abundance changes. Results will be presented for several types of chemically peculiar stars. The future potential of such models will also be explored.
