This example illustrates a use of In-Form for the introduction
of input boundary conditions for TEM1 variable.
As a problem is considered injection into a plane flow.

The inlet flow has a parabolic structure. Inflowing gas has
TEMINL temperature. It is supposed that the specific heat of
the inflowing material is the same as that in domain. In this
case it is enough to specify the inlet temperature value only
in a boundary condition. EARTH automatically multiplies the
inflow temperature TEMINL by the specific heat which prevails
in the cells into which the mass is flowing.
The injection size on a wall is increased proportionally
to its length. Injecting gas has TEMINJ temperature. It is
supposed that injecting gas has the CPINJ specific heat
distinguished from that inside the domain. In this case
in the boundary condition it should multiply the injecting
temperature value on the injecting specific heat and to use
