  This case defines a calculation of the potential flow
  about a half cylinder in a duct in the y-z plane. The
  grid is generated by PIL commands giving a 'shear
  transformation' and is non-orthogonal; so NONORT is set T.

  The potential calculation is contrived by introducing a
  uniform high resistance throughout the flow field. This
  'Darcy' flow is mathematically equivalent to potential
  flow.

  This is done in Group 13 by setting DARCY=T, which
  creates the appropriate PATCH and COVAL settings.  An
  analytical solution exists for this case to which the
  results may be compared (see Milne-Thompson, 1962,
  'Theoretical Hydrodynamics')
