GGU-CANTILEVER: "Displacement boundary conditions" menu item
You can introduce additional displacement boundary conditions anywhere along the wall.

In the example above a rotation "phi" of the wall of 0.0 has been entered 2.0 m below the top of the wall. "wx" and "wy" in the pull-down menu stand for the horizontal and vertical displacements; the direction is defined by means of the sign.
