     Note: January 2009, In order that this could be used with
  the grid-refinement module, SPINTO, the earler use of CONPOR
  with its indicial arguments has been replaced by use of initial-
  value patches such as:
     ** Vehicle body
  patch(BODY1,inival,object,body1, 1,1)
  coval(BODY1,prps,0.0,198)
  wherein the arguments 'object' and 'body1' place the initial
  values in the space indicated by the geometric arguments of
  RSET(B,BODY1,,,,,)

     This is a 3-dimensional Cartesian example in which a solid
  body immersed in an unconfined flow is represented by means of
  'porosities'.  The turbulence of the flow is crudely represented
  by a prescribed constant turbulent viscosity within the fluid,
  together with a logarithmic law of the wall for skin friction.
  The lower (south) boundary of the flow domain, representing
  the road surface, is modelled as a moving wall.

  An impression of the geometry can be gained by examining
  the following sketch.                |
