ProDiMo is a so-called radiation thermo-chemical disk modeling code. Assuming an axi-symmetric two-dimensional dust and gas density structure, ProDiMo calculates the internal wavelength-dependent radiation field, the dust temperature structure, the gas in thermal balance, and the chemical abundances. The two figures below show a typical output of ProDiMo and the flow chart of the code.

ProDiMo provides many options to select different physical and chemical approximations:
- Passive disks heated by the star -- or self-luminous active disks heated by viscosity
- Large range of options to setup the disk density structure:
- multi-zone
- from hydro simulations
- disk + envelope
- hydrostatic vertical structure
- Large collection of optical data for dust opacities:
- adjustable size distribution
- hollow sphere opacities
- position-dependent ice opacities consistent with ice-chemistry
- Dust settling:
- various prescriptions based on about 100 size bins
- various prescriptions based on about 100 size bins
- Options for PAHs:
- adjustable size
- charging states in chemistry,
- opacities in continuum radiative transfer
- detailed computation for heating/cooling via cross sections
- Well-tested ray-based continuum radiative transfer
- benchmarked against MCFOST and MCMax
- MCMax and MCFOST can be used to replace the ProDiMo rdiative transfer
- options to include EUV and X-ray wavelengths
- Large range of central objects:
- Brown Dwarfs
- low-mass, high-mass stars
- AGNs
- Adjustable environment:
- UV background
- infrared background
- cosmic rays and X-ray background
- inclusion of stellar energetic particles (SEPs)
- Large range of line transitions:
- by default, ProDiMo includes about 10000 lines for heating/cooling, can be increased
- from UV to radio wavelengths
- atoms, ions, and molecules
- LTE and non-LTE
- by default, ProDiMo includes about 10000 lines for heating/cooling, can be increased
- Generate images for instrument simulators:
- continuum dust + PAH images
- line fluxes, velocity profiles, and channel maps
- output fits-files for ALMA-CASA

- continuum dust + PAH images
- Flexible chemistry:
- UMIST
- KIDA
- STAND_2020
- private networks
- surface chemistry
- steady-state or time-dependent chemistry
- size-dependent grain charging
