The features in this case are:
* Internal surface-to-surface radiation
* External linear heat transfer from a surface
The external linear transfer coefficient is 10 W/m2/K
* Heat conduction

----------> Y
length of domain = 1.0 m, height of domain = 1.0m
The problem is steady, one-dimensional and convection is absent.
The surface temperature at the left side is 1000K.
The surface at the right side has a heat-transfer coefficient of
10W/m^2/K to an external temperature of 293K. The surface
temperature of the right side, Tw, is calculated.
The PHOENICS solution can be compared with the analytical
solution which shows that TS=968K , and the external heat
transfer rate=6.750kW
