Roller, Interface
Use the Roller, Interface node to add a roller constraint as boundary condition to one of the faces 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.
To apply a roller conditions on the boundaries formed by the edge of the shell, use Roller.
Shell Properties
