  The radial fins are continuous, thin, uniformly spaced.
  Fluid enters the pipe with uniform velocity and temperature;
  A constant temperature is prescribed for both fins and pipe wall.

  Note that the above sketch suggests the the fin projects only
  part of the way towards the axis; but the patch representing
  the fin wall in fact  extends to the axis.
  This is altogther a poor representation of a finned tube,
  no simulation is effected of the reduction in surface
  temperature with diminishing radius resulting from the finite
  conductivity of the fin material.
  This library case should be replaced by one which is more
  realistic.

  The Q1 file contains PHOTON USE commands.

    The locally-defined variables are as follows:

      NFIN           number of fins
      DPIP           pipe diameter
      TWAL           wall temperature
      TIN            inlet temperature
      WIN            inlet velocity.
