Radiation pulse test in optically thin and thick media. More...

Detailed Description

Sets the initial condition for a radiation pulse in an optically thin or thick medium. Radiation energy is initially set as $ E_r=a_R T_r^4 $, with

\[ T_r=T_0(1+100e^{-r^2/w^2})\,, \]

where r is the spherical radius. Uniform values of the gas density and pressure are set in such a way that the temperature satisfies $ T(\rho, p_g) = T_0 $. We also set $ v_x=0 $ and $ \mathbf{F}_r=\mathbf{0} $ in the whole domain. In every setup an absorption opacity $ \kappa=0 $ is chosen.

The following setups are implemented:
