This example shows how  to  use  grid-free  features  of
PLANT  for calculation of scaling factors resulting from
the  presentation  of   circle   inlets   on   Cartesian
coordinate system.

The problem   is  to  introduce  the  correct  mass  and
momentum in-fluxes for the concentric inlets at the east
wall  of  lower  part  of  3D rectangular chamber with a
swirl in annular secondary flow inlet.

It is supposed  that  MARK  of  unity  value  marks  the
primary  inlet  area,  while  MARK=2  is used to specify
secondary inlet cells.

Two circular holes are "drilled" at the west face of the
domain  by  way  of  SPHERE  function.  The  provide the
primary inlet of 2 m diameter (  MARK=1)  and  secondary
