Default reflecting the geometry

Hi; when you have a simmetry plane on the left hand side of a model, how can you reflect the geometry and the results? The macro on adapco online shows how to do it from left to right (positive z direction) with 'cgen' and then the same thing with 'dgen'. I try changing the the direction for a negative value, that is "CGEN,2,VOFF,CSET,,,VREF,1,3" with "CGEN,-2,VOFF,CSET,,,VREF,1,3", or even tried 1 and 3 but it did'nt work, it seems to be creating a second array of cells in the same location as the original one! Does this mean I have to repeat my geometry? Many thanks. Isidro

Did you also create a new set of vertices (which will be mirrored with the offset VOFF) *before* using the command CGEN? As you create new cells, you need also to create new vertices...
