This example illustrates the Domain-partitioning technique.
This steady case simulate simple flow in xy plane. On the west
side there is an
inlet
and the north and east sides are
outlets
.
The south side is a
wall
with constant temperature.
In the west-south corner of the domain area there is a
source of a pollution concentration.
The solved area is divided into two parts.

The solution in each part is made in a separate run.
The TROB$
1 transfer object on the east boundary is formed
at the end of the first run by means of an '(export' In-Form stat$
ement.
It stores the values of the outlet mass flux and the dependent
variables values on this boundary to transfer them to the second$
run.
The second run reads the information at the west boundary from the
TROB1 ob$
ject by means of an '(import' In-Form statement.
The third run simulates the flow without the domain-partitioning
technique for comparison with the results of the previous runs.
The Q1 contains PHOTON USE commands.
