No worries.
\nTo be honest these part or at least the named selections are not very similar with each (different amount of nodes in each face and distribution) other which one would expect, so something is strange – in the software you use to generate the lattices I would start with these faces being completely planar so it does not curve them, because a symmetry plan should be flat to make life easy. Once this is done (flat symmetry faces) then:
\nSo try to 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). You need like in the video of course to have 2 Displacement BC, one for each symmetry plane.
