mod_rhd_phys Module Reference

Radiation-Hydrodynamics physics module Module aims at solving the Hydrodynamic equations toghether with the zeroth moment of the radiative transfer equation. A closure is provided by the flux limited diffusion (FLD)-approximation in the mod_fld.t module. See [1]Moens, N., Sundqvist, J. O., El Mellah, I., Poniatowski, L., Teunissen, J., and Keppens, R., “Radiation-hydrodynamics with MPI-AMRVAC . Flux-limited diffusion”, Astronomy and Astrophysics, vol. 657, 2022. doi:10.1051/0004-6361/202141023. For more information. Another possible closure in the works is the anisotropic flux limited diffusion approximation (AFLD) described in mod_afld.t. More...
