DISPLAY
An inviscid fluid flows steadily in a direction normal to a flat
plate. Since the potential-flow equation involves only diffusion-
type terms, sources, convection and transient terms are switched
off automatically within EARTH.
The geometry of the problem is as follows:
frictionless wall
-----------------------------------------------------
-------->
----> --------> ---->
^ ----> Plate ---->
| |
y| ---------------------------|-------------------------
| frictionless wall
z--->
The plate is introduced by the setting of PRPS=199
for the appropriate cells.
