| Abstract: |
We present a comparison of two autonomous, methodologically different
radiation hydrodynamic codes, FLARIX and RADYN, and their use to model the solar flare processes.
Both codes can model the time evolution of a 1D atmosphere heated by a specified process, e.g. by
electron beams propagating from the injection site in the corona down to the lower atmosphere.
In such a scenario time scales can be rather short and lead to fast heating on even sub-second time scales.
Our aim is to compare the FLARIX and RADYN codes using exactly the same setup and model conditions.
Although such a comparison has never been done successfully before for this type of codes,
we will present a close agreement between the time evolution of the modelled atmospheric structure
for a test case of electron beam heating. |
