    Cases 110 to 114 illustrate how "porosity" values may be used
    to introduce not only geometrical data, but also variations in
    thermal conductivity, specific heat and heat-transfer coeff.
    In case 110, the cross-section and other properties are uniform.
    Subsequent cases introduce non-uniformities, by way of porosity,
    one by one.  A sketch of the geometry for case 110 follows:
                   /--/|
                  /**/ |
                 /**/  |
                /**/   |
               /**/  <------- surface in contact with
              |--|     | ^    surrounding fluid
              |**|     | |    at temperature = 0.0
              |**|     | |x
              |**|     | |
        ///// |**|    //////////////////////////////////
       ////// |**|   //////////////////////////////////
      /////// |**|  ////// base at temperature = 1.0 /

    That it is possible to act in this way does not mean that it
    is necessary or even recommended.

    These cases were very early entries to the library, and have be$
en
    retained for historical interest. However, the treatment of H1
    as though it represented temperature is valid only for a
    constant specific heat; and, in the final case of the series,
    the specific heat is supposed to vary.

    Nowadays, use of TEM1 is recommended rather than H1; and In-Form
    provides a much more convenient way of introducing variations of
    properties and boundary conditions.

  This is case 110, but with the fin tapering from its full
  thickness at x=0 to zero at x=XULAST.

  This is effected through EPOR and VPOR settings.

  ENDDIS
  DISPLAY
  In addition to the taper of case 111, the material changes at
  x=XULAST/2.

  Here the thermal-conductivity change, from COND1 to COND2, is
  effected by changing the area porosity.
