DISPLAY
A plate is held centrally in a square box through the wall of
which flows an inviscid fluid.
The velocity potential at the walls accords with the formula:
POT = aa * x + bb * y
where aa = -1 and bb = -1
(which can of course be changed by editing the Q1 file)
The task is to compute the flow field within the box.
In-Form is used in order to specify the boundary condition.
The plate is represented by setting area porosity to zero.
The Q1 uses SOURCE In-Form statement.
The Q1 contains PHOTON USE commands
