*********************************************************
This case concerns the prediction of air flow and temperature
distribution in and around a closed metal box, which contains
two heat sources. These liberate 5W and 7W respectively. The
box is cooled from the outside by air at 20 deg C being blown
at 1.5 m/s.
The case takes about 45 min to run on a 486/50. The conjugate
gradient solver is used to improve convergence of the
temperature equation.
The results can be plotted in PHOTON by typing 'use q1'
