I have been trying to visualize the symmetric half of a 2D beam along its symmetric YZ plane after analysis but the mirror option does not work well for this case. Somehow the mirror part is superimposed on the existing part when I try to display it. I am using a symmetric BC XSYMM U1=UR2=UR3=0 at the symmetric edge of the beam. Below I am attaching snaps of the same. Cheers!
