Q. In 11.0, newly created models which have bolt pretension load do not automatically run two load steps like they did at 10.0.
But the documentation states "When a Bolt Pretension load is present, the simulation automatically executes 2 steps...."
Is this a bug?
A. This is a documentation bug. The change to the code was intentional to give users more control over how bolt pretension is implimented and to make this load more consistent with other loads. The documentation will be corrected to reflect this change at 12.0. In general, for enhanced convergence, users are advised to set up two load steps with LS1 applying the load and LS2 locking the load. This also makes verification of the bolt working load easier.
