The numerical schemes for solving the radiative transfer in the co-moving frame of reference have been developed by Mihalas and co-workers 30 years ago. The most elaborate codes can cope today with many hundred explicit non-LTE levels or super-levels and account for metal-line blanketing. The limited agreement with observed spectra indicates that the model simplifications are still severe. One approximation that has to be blamed is homogeneity.
