  1. i don't know. i haven't had experience for pretension in optistruct. i have tried to change direction, but i had the same result. solution goes, but result i don't like. do you mean that we can't choose preload force direction?
  2. Hi, colleagues! why does not increment increase?
  3. Wow! so much contact pairs are in your model!=) it's not good model for first issue=) you should do some simple test at first=) i will check this, but i am newbie in optistruct. )
  4. could you show pics of your model. both variants are right, every suggestion does work good, but you should decide how to solve you issue by yourself. do you have test result for your weld? do you make crushable weld? advantage for spotweld is that you do not make shell mesh.
  5. thanks, @Mario! i will try to do it.
  6. @Pranav Hari! hello. i have a large model there i should add some details. detailes i have meshed separatly=) but when i had added detais to main file to connect models i had a issue with long response. i need all components of model. is it clear?=)
  7. Hello, collegues! my question is how to perform hm for large assemble working? i have a model which consists more than 4 mln elements and i am upset... every operation i'm waiting for a long time. why does HM work so long? i understand if HM saves my large file or checks all model. but i have masked large part of model and work with less than 10 details which consist average 1000 elements. i was remeshing/connecting each over. and i was waiting every operation 1 minute or 2 sometimes... my computer isn't weak. any idea? thanks a lot!
  8. hmmm, it is interesting feature. could you tell about it or give a link? i have been working in abaqus and i think i can help you, but i didn't use and know about this feature.

    part of result

    Hi, @Q.Nguyen-Dai optistruct. i need large information, i have reduced my output as good as possible. i called only one part for stress result, but duration of simulation 60 s, and stend frequency increases to 55 Hz.
  19. hello all! i have a question! how to load just part of result file? i have a more than 31000 frames and how you can understand i can not load all result=( what do i do? i take first 4000 frames->derived result->step and i have new subcase with 4000 steps (frames). but it loads so long too. have you any idea? thanks a lot!
