From the image misinterpreted it as solid and this condition applied to end face. When you apply displacement condition to a face in a solid, it also constrains the rotations inherently, because to rotate, nodes must change relative coordinates, which needs them to translate, but again translations are constrained so the rotations are not possible.


For beams or shells, displacements when applied to a single node, it can rotate without changing their positions, when fixed support is applied, it also constrains the rotations (by d, all, all command I mentioned), but when you want to constrain rotations as well, you will need to do that using remote displacements.
