  DISPLAY
  Hot air flows steadily through a box having two cooled walls.

  A centrally-placed metal block takes up an intermediate
  temperature, under the influences of conduction, convection and
  radiation.

  Values which it may be interesting to vary are:
  * gas absorptivity/emissivity coefficient:  EMISS
  * gas scattering coefficient             :  SCAT
  * hot-wall emissivity                    :  EMISH
  * cold-wall emissivity                   :  EMISC
  * block emissivity                       :  EMISB
