  The flow is isothermal and the example duct is a cylindrical
  channel curved curved through 180 deg. The point of this case
  is to display the good behaviour of PHOENICS with fully 3D
  flows.

  Since the 3D phenomena take place downstream of the bend, a
  length of 8 diameters is considered. The upstream length is
  only 2 diameters since the slight influence of the curved duct
  in the inlet region.

  It is possible to redefine the number of cells in each direction.
  The 2D geometry can be changed in the following aspects:

     - the Radius Rc.
     - the angle Angu of the curvature.
     - the lengths of the upstream and downstream regions.
