DISPLAY
The problem considered is a steady, incompressible, turbulent
flow across a smooth flat plate with zero pressure gradient,
beginning downstream of the inlet. The high Reynolds form of the
Spalart-Allmaras turbulence model with wall functions is used.
This case is based on the NASA verification case
https://turbmodels.larc.nasa.gov/flatplate.html.
