DISPLAY
This case involves steady, turbulent flow over a backward-facing
step, of height h, in a two-dimensional channel of width 3*h.
The calculations are started at a distance 4h upstream of the step
and terminated at a distance 16h downstream.

** Phoenics core library case 290 with the additive correction
multi-grid solver with LU-decompsition smoother (LACM)
** Information required to use this solver is:
1. CSG3=LACM to specify the name of the solver.
2. ICNGRB <= phi <= ICNGRC to specify which phis to solve for,
all phis in this range will be solved, though P1,U1,V1,W1
are also solved by default.
3. NFUSER=19*NX*NY*NZ for workspace.
4. USEGRX=T;USOLVE=T to ensure that it is called from grex.
5. IG(11) To specify the number of grid levels
