Steady flow over a 2D backward facing step
This canonical case is based on the description by Driver and Seegmiller
D.M. Driver and H.L. Seegmiller. Features of a reattaching turbulent shear
layer in divergent channel flow. AIAA Journal, 23(2):163–171, 1985.
where the mesh is based on the Langley Research Center Turbulence Modeling
Resource set-up provided at:
https://turbmodels.larc.nasa.gov/backstep_val.html
The Reynolds number based on the step height is Reh 36000 for which the
stated reattachment length is at 6.26 +/- 0.1 x/h
The Allrun script will run the case and generate graphs showing the wall
shear stress and velocity profiles at various cross-sections.
