  DISPLAY
  A gas stream enter steadily into a 2D thick-walled channel, the
  outer surfaces of which are held at different temperatures.

  A solid block within the vessel takes up an intermediate
  temperature, under the influences of convection and radiation,
  in which the gas participates.

  The task is to determine the temperature distribution in the bloc$
k.

  Values which it may be interesting to vary are:
  * gas absorptivity/emissivity coefficient:  EMISS
  * gas scattering coefficient             :  SCATT
  * emissivities of north wall, south wall and block:
                            EMIS_N , EMIS_S and EMIS_C
  * their material indices: MAT_N , MAT_S and MAT_C
  * their temperatures    : TEM_N , TEM_S and TEM_C
