   This case  concerns 2D  incompressible, laminar/turbulent
   flow over back-facing step.  Geometry of the problem  was
   taken from GAMM-workshop 1984 (Re=50, 150, 500). A  fully
   developed parabolic laminar flow profile is prescribed at
   the inflow.

   Computational domain comprises fine grid, which is embedded
   after the step. Sizes (NXFG, NYFG) and refinement ratios
   (IFCX, IFCY) of the fine grid may be modified:

               NYFG                             
             
   Simulation of the turbulent (LTURB=T) flow can be carried
   out with either the Lam-Bremhorst low-Re extension of the
   Chen-Kim  K-E model (LTWOL=F)  or the 2-layer  low-Re K-E
   model (LTWOL=T).

   User can  use higher  order convective  schemes (MINMOD-,
   SUPER-BB-, SMART- or QUICK-scheme) by setting appropriate
   name of the scheme for solved variable.
