Comparison is made of the heat flux predicted by IMMERSOL with
that predicted by classical methods for a problem presented in the
Irwin in 1995.

A 3m x 3m furnace is in question, long enough for variations in
the length direction to be neglected.The top wall is held at
1400 deg K,the side walls at 1700 deg K, and ths floor at
600 deg K.

All surfaces have an emissivity of 0.5.

The task is to predict the heat flux to the floor, which Mills
calculates as 159 kW/m**2
