This example illustrates a use of In-Form for the introduction
of inlet, outlet and wall boundary conditions.
As a problem is considered heat transfer in a plane channel.
//////////////////// North Wall ///////////////////////

^ y
|-------> x-direction
The inlet flow has a uniform structure.
The coefficient of outlet boundary condition is set as uniform.
North and south walls are immobile and have the uniform
temperature.
There are two cells in Z direction. First cell is used for
sources setting by one formula. Sources at second cell are
set by coval function with two formulas for coefficient and
value.
Application of special flags.
North wall boundary condition use PATCH command with NORTH
type. Therefore wall velocity is set by In-Form statement
with LAMWALL flag.
South wall boundary condition use PATCH command with SWALL
type. Accordingly wall velocity is set by In-Form statement
without special flags.
NOTE: Special flags can not be used together with coval
function.
If the boundary conditions on north and south walls are
identical the results of calculation should be symmetric.
The fields of dependent variables at first and second
IZ cells should be edual.
