  1. Hi all, I am exploring the Optistruct pretension manager capabilities instead of preloading the bolts in a "manual" way. Do you know if Optistruct iterates to find the right preload values starting from my input? Example: I need to apply a bolt preload of 20000N. Once applied, I calculate the sum of the gpforces on a section of the bolt and I find the total force to be 18000N. So I have to increase the input preload to 22000N to obtain an actual preload of 20000N. This is because of the elasticity of the components connected. Does Optistruct iterate starting from the input value to find the right preload value? As an additional question, is there a faster way in Hyperview to measure the gpforces on the section of the bolt? It is time-consuming exporting the value to excel to sum them all. Thank and Regards
  2. Hello Everyone!! I want to do a Drop analysis of an assembly. The Assembly consists of more than two parts connected by bolts. I have the pretension Loads. Is it possible to apply (include) the pretension loads for the drop analysis (explicit)? Or is there any other way to simulate the effect of pretension? Kindly advice. Thanks in advance, -RathinaVel
