Pretension Contact and surface

Hi

I am trying to run a model using pretension manager. I have two major concerns about the tutorial about pretension manager.

1. The contacts are set to be freeze. why freeze? and if it is an approximation, what kind of contact type for bolt surface must be set for an accurate analysis using pretension manager.

2. In tutorial, the location where the surface of pretension-load in 3d bolt have defined, seems to be selected arbitrary. Howerer in my anlaysis this loctaion(where the surface of pretension is defined) effects the results.

 

Thank You in Advance

    I am not sure but I think the reason is that to reduce the computation time.

    I do have the same question.

    Yes freeze is for reducing the computation time, but which contact should be used to get correct results?
