rotational constraint

I am trying to do a static analysis of a cantilever beam whose one end is fixed.
In the other end I am applying forces axially and also in the transverse direction. But I what this end to be rotationally restraint, but can undergo an axial and transverse deflection. The final deformation of the beam will look somewhat like the attached figure.
While I am able to do everything else, i am not able to figure out! how to give a rotational restraint constraint. Someone please help!

There will be options to add contraint type as rotational and translation constraint

Assuming that you are using Solid Mechanics, there are two direct approaches:
Approach 1:
Add a Rigid Connector to the end boundary and constrain its rotation.
Approach 2:
Add a Symmetry condition to the end boundary, and make use of the settings in its Normal Direction Condition section.
