Pinned constraint

A pinned constraint defines an axis of rotation. Once you select a cylindrical face, a cylindrical coordinate system is created. The R and Z directions are fixed, and the theta (rotating) direction is free. All rotational DOF are also free.

Note:

When you define a pinned constraint on geometry, a local coordinate system is created and applied to the underlying nodes. If local coordinate systems already exist at these nodes, the constraint's coordinate system may overwrite them. For example, if you define a constraint on a location where spring elements are defined, the constraint's coordinate system may overwrite the spring element definitions.
