When your upstream External Model source file includes bolt pretension loads, an Imported folder appears beneath the Connections parent folder when you open the file in Mechanical. This object is a simple group folder. It contains the child object: Bolt Pretensions (or Premeshed Bolt Pretensions). The data associated with the imported bolt pretension is provided through the Worksheet.
Note: For Premeshed Bolt Pretensions, the nodes at the pretension section interface are coupled using CP commands to provide continuity for all other analyses types where Bolt Pretension is not applicable.
