TALK=T;RUN(1,1) DISPLAY 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: NXFG 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. ---------------------------------------------------------- ENDDIS PHOTON USE p ; ; ; ; ; msg Computational Domain: mgrid 1 k 1 mgrid 2 k 1 col 2 msg Press Any Key to Continue... pause cl set vec av off msg Velocity Vectors: mvec 1 k 1 sh mvec 2 k 1 sh msg Press Any Key to Continue... pause cl msg Contours of Pressure: mcon 1 p1 k 1 fi 0.01 mcon 2 p1 k 1 fi 0.01 pause cl msg Contours of U1-velocity: mcon 1 u1 k 1 fi 0.01 mcon 2 u1 k 1 fi 0.01 msg Press Eto exit PHOTON ... pause ENDUSE SCHMBEGIN VARNAM UC1 SCHEME MINMOD VARNAM VC1 SCHEME MINMOD VARNAM KE SCHEME MINMOD VARNAM EP SCHEME MINMOD SCHMEND ************************************************************ Group 1.
