This example illustrates the use of In-Form transfer objects
for a 2D convection-diffusion problem in the y-z plane.
This case simulates flow in a channel.
The inlet flow has a uniform structure.
North and south walls are immobile and have uniform
temperature. The source of a non-dimensional concentration
is set in the first cell only.
The solved area is divided into three parts.
The solution in each part is made in a separate run.

The
TROB1 transfer object at the high boundary is formed at the
end of the first run by means of an '(export' In-Form statement.
The second run reads the information at the low boundary from the
TROB1 object by means of an '(import' In-Form statement and
creates the
TROB2 transfer object at the high boundary.
The third run reads the information at the low boundary from the
TROB2 object.
The fourth run simulates the flow in the whole channel without
the partitioned-terrain technique for comparison with the previous
three runs.
