TALK=T;RUN(1,1) DISPLAY Lid Driven Cavity Flow Problem (Chris J.Weire 16/3/94) Moving Wall > 1m/s Fine Grids ^ 1.0 v <> 1.0 This case demonstrates the use of 4 zones of Fine Grid Embedding in the corners of the cavity, where large velocity & pressure gradients occur. Use of the FGE zones enables recirculations to be detected without an excessively large mesh. The dimensions of the main mesh are set through NX1,NY1, and the power law exponent in POWER in this Q1. Likewise, MBFGE refinement factors are set through IFICX, IFICY. Setting these to 1 creates the equivalent of a normal power law mesh. Q1-file contains Photon Use information. --------------------------------------------------------- ENDDIS PHOTON USE p ; ; ; ; ; mgrid 1 k 1 mgrid 2 k 1 col 2 mgrid 3 k 1 col 3 mgrid 4 k 1 col 4 mgrid 5 k 1 col 5 msg This is the grid, press return to continue... pause set vec av off mvec 1 k 1 sh mvec 2 k 1 sh mvec 3 k 1 sh mvec 4 k 1 sh mvec 5 k 1 sh msg Velocity Vectors, press return to continue... pause set con scale range on set con fi depth 4 mcon 1 p1 k 1 fi 0 0.02 mcon 2 p1 k 1 fi 0 0.02 mcon 3 p1 k 1 fi 0 0.02 mcon 4 p1 k 1 fi 0 0.02 mcon 5 p1 k 1 fi 0 0.02 msg Enter e to end, or any Photon command to continue...
