   **********************************************************
   This Q1 concerns the flow of molten glass through a channel
   lined with refractory brick, and the air above it.

   The glass enters at 1150 deg C, and loses heat to the walls
   and floor at 2kW/m**2. Some heat is transferred by contact
   to the air. The glass (userm1) has a viscosity of 0.1.

   The case takes about 10 min to run the 30 sweeps set on
   a 486/33, but requires several hundred sweeps to converge.

   Results can be viewed in PHOTON by typing 'use q1'
