The purpose of creation of this case is a demonstration
of the transfer objects feature.
This example explores the distribution of pollution on a
reasonablylarge region of ground. The use of transfer objects
permits the calculation of unidirectional flow on small parts,
one after another.
The solved area in this example is divided into four parts.
The solution in each part is made in a separate run.

HIGHTRO1
and EASTTRO1 transfer objects on the high and
east boundaries are formed at the end of the first run by means
of two '(export' In-Form statements.
They store values of outlet mass flux and concentration on these
boundaries to transfer them to the second and third runs.
The second run reads the information at the low boundary from the
HIGHTRO1
object by means of '(import' In-Form statements and
at the end of calculation dumps it at the east boundary in the
EASTTRO2
object.
The third run reads the
EASTTRO1
object and forms the
HIGHTRO3
object.
The fourth run reads the information from
HIGHTRO3
and EASTTRO2 import transfer objects at the low and west
boundaries.
In general there can be any number of transfer objects.
Each run simulates the distribution of pollution in one part.
The wind profile at inlet boundaries is set by means of
In-Form statements as a logarithmic velocity profile.
The ground relief (HIG variable) is calculated by this
In-Form formula.
The MARK variable
defined
by In-Form is used for the image of ground relief in Photon.
The ground roughness is simulated by a change of air density
driven by the height of an atmospheric layer. Density of air is
calculated
by barom$
etric formula by means of In-Form.
The last, fifth, run simulates the flow in the whole region
without partitioning. It will be useful as a comparison
to the previous runs.
