This case illustrates the use of PIL to set up a "Couette flow",
i.e. that which arises between extensive surfaces, separated by a
constant distance, and sliding relative to one another.

The flow is laminar, and the flow has uniform properties.

Four equations are solved, namely for velocity, W1, and for three
scalar quantities A, B and C which are distinguished only by
having Prandtl Numbers of 1.0, 0.1 and 10.0 respectively.

Each variable is given the value 0.0 at the lower (south) wall
and the value 1.0 at the upper (north wall).

The computed profiles are, of course, linear; and the only
differences between the solutions for the four variables lie in
the sources and sinks at the walls. These are largest in magnitude
for C and smallest for B.
