  The atmospheric structure of chemically peculiar stars deviates from that of
normal stars with similar fundamental parameters due to unusual chemistry,
abundance inhomogeneities and the presence of strong magnetic field. These
effects are not considered in the standard model atmospheres, possibly leading
to large errors in the stellar parameter determination and abundance analysis.
To tackle this problem we used the state-of-the-art opacity sampling model
atmosphere code LLmodels to calculate comprehensive grid of new generation
model atmospheres for magnetic CP stars. This grid covers the whole parameter
space occupied by SrCrEu and Si-peculiar stars, taking into account
characteristic temperature dependence of the chemical abundances. Here we
present the first results of our model atmosphere calculations.
