  1. Programming in Inspire 2017

    By the way, if I use Optistruct or Hyperworks, is it possible to program the material properties or other properties? I'm also planning to program mesh type (I would like to set as beam elements rather than solid elements)
  2. Programming in Inspire 2017

    Greetings, I'm thinking about optimizing a 3D-truss structure by Inspire 2017 7305. And I would like to know whether it is possible to program the property of materials. I'd like to design a part of the structure as a tension wire. So, I'd like to define its compression stiffness as zero, and its tension stiffness as non-zero. If it is not possible, I would appreciate if anyone can tell me how to do that (though it may be beyond the scope of this website).
  3. Programming in Inspire 2017

    Hi Felix, Unfortunately, it is still a concept, so I haven't made any models... First thing I have to do is to accurately model 3D truss structures in Inspire. But thanks anyway. Best regards,
  4. Setting of Weighting function

    I'm sorry for my late reply... Thank you very much for your detailed explanation.
  5. Setting of Weighting function

    Greetings, I have a basic question about the optimization in Inspire 2017 7305. It is possible to maximize the stiffness as well as the natural frequency of structures in Inspire, but how can I decide the weighting function of these two objective functions? In general, in such multi-objective optimizations, I think it is necessary to adjust a weighting function. Maybe it is performed automatically by Inspire, but how is it done? On which is focused more - maximization of stiffness, or maximization of natural frequency? Thanks in advance.
  6. Optimization Error

    Thank you very much for your explanation, Mario!
  7. Optimization Error

    I posted this topic on wrong place (FAQs), so let me post this again here (General Discussion). Error message appears and says "Loads or supports are inappropriate", but I cannot find any problem with my settings. I'd like to know what is wrong with my settings of loads or supports. Thank you. model0817_2.stmod
