     25The rad. energy in the grid at t=0, assuming no 'sources' is given by the temperature field through the term:

     27[[latex($E=4\pi B(T) = aT^4$)]]
     28
     29In the code the constant out in front is given by "scalerad". Checking a uniform ambient medium with this expression for Erad, shows that Erad at t=0 is given by scalerad*T^4^. Thus, any gas with finite temperature is producing radiative energy in the grid through black body radiation. Since
