At the before how do we solve the bolt pretension problem?
At now if we have the bolt we can consider it bolt pretension in the analysis.
And I want to ask at before if we have the bolt and we just neglect the pretension.
How do we solve the bolt problem in the case? Just set the bolt to be freeze contact in the model?
We all use the 3D pretension now. There has a question about what different between 1D and 3D pretension.
