Selected 2D results of disc models after stage 3 as function of radius r and relative height over the midplane z/r. Upper row: hydrogen nuclei density n_〈H〉(r, z). Second row: dust temperature structure T_d(r, z). Third row: local dust-to-gas ratio. Bottom row: classes of solid mixtures(r, z); see Table 2. Additional dashed contour lines mark the vertical Rosseland optical depth τ_Ross = 1 and τ_Ross = 100. The black areas in plots in the two lower rows marks the end of the GGchem modelling domain n_〈H〉 > 10⁷ cm⁻³.
