Description

-----------



RADIS is a nonequilibrium infrared emission and absorption line-by-line code.



Written as a general purpose radiative solver, the code is built around the HITRAN,

HITEMP and CDSD databases for molecules in their electronic ground state. Energy

levels are read from tabulated databases or calculated from Dunham developments.

Boltzmann, Treanor, and state specific vibrational distributions can be generated.

A modular architecture makes it possible to add new species without modifications

to the core code. Thus far, |CO2|, CO are featured for non-equilibrium calculations,

and all species present in the HITRAN database are featured for equilibrium

calculations. To fit experimental spectra, RADIS includes a line survey tool, an

interface with a look-up database to improve fitting convergence times, and a

multi-slab module with a radiative transfer equation solver to reproduce line-of-sight

experiments. Validation cases against existing spectral codes and experimental

results from various plasma sources are included.



The code is available for use and modifications on `GitHub <https://github.com/radis/radis>`__

under a `GNU LESSER GENERAL PUBLIC LICENSE (v3) <https://github.com/radis/radis/blob/master/LICENSE>`__,

i.e., that modifications must remain public.
