  DISPLAY
    Radiative heat transfer in a 3D box is considered. Four of the
  walls are kept at constant but different temperatures; the other
  two walls are assumed to be adiabatic. The emissivities of the
  walls are assumed to be equal. Further background information is
  supplied in cases 550 and 551.
