In this example, the two-equation k-epsilon turbulence model is used and generalised wall functions are used at the north boundary of the domain. The recommended linearization practice, KELIN=3, is employed. 10 "hydrodynamic iterations" are used at each z-location in order to reduce the number of sweeps needed for convergence. PHOTON commands are attached for convenience. ENDDIS ************************************************************ Group 1.
