TALK=T;RUN(1,1) DISPLAY This simulation concerns incompressible, turbulent flow over a backward-facing step in a two-dimensional closed channel, as described fully in library case T103. For this case, the standard form of the k-e turbulence model is known to underpredict the reattachment length XR by about 14%. Calculations may be made with the high-Re form of the standard k-e model or the 2-scale k-e model, which is selected by putting TSKE=T.
