Non-LTE radiation-hydrodynamics module for the code PLUTO

The numerical module is an upgraded version of the LTE radiation-hydrodynamics module implemented in the PLUTO code, originally developed by Kolb et al. (2013, A&A, 559, A80) (available at this link for the web site), extended to handle non local thermodynamic (non-LTE) regimes.

An operator-split method is employed, with two substeps: the hydrodynamic part is solved by the solvers already available in PLUTO, the non-LTE radiation diffusion and energy exchange part is solved with an implicit method. The module is fully implemented in the PLUTO environment. It uses databases of radiative quantities that have to be provided independently by the user: the radiative power loss, the Planck and Rosseland mean opacities.

The module is written in the C programming language.

Features

  • Fully parallelised with MPI libraries;

  • Usable with the classical hydrodynamics (HD) and magnetohydrodynamics (MHD) PLUTO modules;

  • Supports Cartesian, cylindrical and polar coordinates;

  • Non-LTE opacities and radiative losses have to be provided by the user;

  • Makes use of PETSc solvers to solve the radiation part.


The module is available under request, to the scientific community.
