      In the early years of PHOENICS, the energy equation was solved
      with enthalpy as the dependent variable; temperature was
      treated as an auxiliary variable, the values of which were to
      be deduced from those of enthalpy by way of the specific heat
      capacity of the fluid.

      However, this was troublesome when so-called 'conjugate heat
      transfer' problems had to be solved with heat-conducting
      solid materials immersed in fluids; for each material could
      have a different specific heat.


      This library case was introduced at the time at which solving
      for temperature directly was introduced, this being achieved
      by use of the material-marker variable PRPS, wht value of
      which at each point indicated what material, and therefore
      what specific heat, was to be used there.

      The steady flow in a cavity with one moving wall is modelled.
      The stationary walls are at one temperature, and the wall
      moving with a constant velocity is adiabatic

      Within the cavity is a heated block of steel. The fluid is
      water.
