2-dimensional, Cartesian, steady, elliptic simulation

This case is based on core-library case 249, the square cavity
with a moving lid. The lid temperature is held at 293 K and the
base at 273 K. The side walls are adiabatic.

In addition to conduction and convection in the fluid (namely
air), radiation is supposed to take place from wall to wall.
For simplicity, each wall is divided in two equal patches. Each
side-wall patch takes up a temperature which corresponds to a
zero net heat flux.

To enable the effect of radiation on the temperature distribution
to be clearly seen,
(1) the moving-lid velocity is set to zero, so that the
temperature distribution must be symmetrical; and
(2) the scalar variable C1 is solved, the properties and boundary
conditions being the same as for TEM1, excapt that, of course, its
values are uninfluenced by radiation.
