DISPLAY
An inviscid fluid flows steadily in a direction normal
to a flat plate. Since the potential-flow equation which
represents this situation is identical with that for flow
through a highly resistive medium obeying Darcy's law, it
is the latter problem which is solved, a device which is
effected by the command DARCY=T. This entails that the
pressure values computed correspond to 1.0E4 times the
velocity potential.
SELREF is set=f in order to prevent premature termination.

The geometry of the problem is as follows:

frictionless wall
