DISPLAY
This case concerns plane, two-dimensional, incompressible
flow through a 180 degree turnaround duct. The flow exhibits
large streamline curvature together with flow separation near
the bend exit next to the inner surface of the duct.

Calculations are made with the high-re k-e model and the
high-Re 2-scale k-e model. The latter is selected by setting
TSKE=T in the Q1 file. The fine-mesh calculation employs a non-
uniform mesh of NY=25 and NZ=80, for which the solution is not
as yet grid independent.

For speed of computation, this library case has been set up to run
for 20 sweeps only on a coarse mesh of NY=20 by NZ=40. About 400
sweeps are required for complete convergence.
