The Ansys Innovation Space website recently experienced a database corruption issue. While service has been restored there appears to have been some data loss from November 13. We are still investigating and apologize for any issues our users may have as a result.

Hi

Perhaps this post helps (shows how to rotate with nrotate command, and apply displacements in tangential UY or radial dir. UX of CSYS,1 - cylindrical system)

https://innovationspace.ansys.com/forum/forums/topic/how-to-apply-dof-in-the-radial-and-tangential-directions-on-a-half-circle/

All the best
