Roller
Use the Roller node to add a roller constraint as boundary condition on the boundaries formed by the edge of the shell. The displacement is zero in the direction perpendicular (normal) to the boundary, but the boundary is free to move in the tangential direction. A Roller condition is similar to a Symmetry condition, but the latter has more options.
To apply a roller condition on one of the faces of the shell, use Roller, Interface.
Shell Properties
The selection in this section only acts as a filter for the boundary selection.The constraint is applied all through the thickness of the shell.
All other settings for the Roller node are described in the documentation for Roller in the Solid Mechanics interface.
