Numerical Schemes validation example:
2-d x-y, Cartesian, steady, elliptic simulation
The problem considered is turbulent flow over a backward facing
step, as studied experimentally W.D.Moss et al (1st Symp. on
Turb. Shear Flows, Univ. Park, Penn., USA, Vol.II, p13.1, 1977).

The Reynolds number based on step height H is 5E4 and the
expansion ratio is 1.1. The inlet is specified as a uniform
inflow located 12H upstream of the step. The outlet plane is
located 30H downstream of the step. This Q1 uses quadratic-upwind
differencing for the velocities, and Koren's bounded scheme for
the turbulence variables.
