    5252That is, a photon travels an infinite distance before it interacts with another particle -- i.e. we are in the free-streaming limit.

     54In this case, the rad diffusion equation becomes:
     55
     56[[latex($\frac{\partial E}{\partial t} = 0$)]]
     57
     58That is, the radiation diffuses instantly through the grid. Recall, how this radiative energy ''couples'' to the gas is given by the coupling term in the radiation equation, not shown here.
