One of the latest developments of ProDiMo is to include ice opacities in the continuum radiative transfer.  A new paper by Aditya M Arabhavi et al. (submitted to A&A) describes how the ice abundances, resultant from the disk chemistry, can be used to calculate position-dependent (dust+ice) opacities.  Since the disk chemistry uses the results from the radiative transfer, but now the opacities depend on the chemistry, we need to run iterative models.

The disk integrated flux, i.e. the spectral energy distribution (SED) does not show the 3um ice absorption feature in this model, because that flux is dominated by scattering and thermal emission from the disk surface, which is ice-free.  However, we can still find the 3um ice absorption feature when we analyse the intensities coming from the dark lane.
