Please read through my post carefully - we can not use symmetry so do this instead which is equivalent to a symmetry condition:

So add a Displacement boundary condition (BC) as shown in the image below, and then restrain the displacement (set it to 0)

**in the direction perpendicular to these symmetry faces**(just as shown in the video above in the previous post). Finally you need to have 2 Displacement BC, one for each symmetry plane.

So use displacement

Also search the internet to understand what a symmetry BC is (just restrains degrees of freedom that are/move perpendicular to the symmetry plane - so for 3D elements either UX,UY, or UZ) - see this video for a simple example:

Thank you
