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
