For the torsion bar only, you say you have "tried both remote displacement and remote force load neither work".  In what way does it not work?

Upload a Workbench Project Archive .wbpz (NOT .wbpj) file by using the File, Archive menu to a file sharing site such as Google Drive, OneDrive or Jumpshare and paste the link in your reply. I will have a look at both the full system as well as the torsion bar only.  When you reply, also say what version of Ansys you are using.
