  1. Thank you very much for your advices! I have tried to optimize with volume fraction constraint and compliance minimization and have got the following result: Then I imported the result to HyperMesh by means of OSSmooth. But the structure is still too heavy. 1) Could you please recommend the rational constraint choice sequence in this case? And also I tried to conduct topology optimization procedure for bigger design space: But the result structure is not continuous. 2) So how I can get the continuous structure instead of discrete? Best regards
  2. Thank you very much for your advices! =) But how can I get a solid structure as a result, not shell? Can I apply some settings to control it? Best regards
  3. Hi! I have a question connected with topology optimization results. I optimized solid Design Space, but as the result I got shell structure when I choosen equal values on the result panel. 1) Could you please explain why is this shell and how Optistruct calculates mass in .out file in this case: mass of solid or shell? 2) What is the physical difference between element densities as 0.8 instead of 1? Best regards

  5. Good day! How to restart an Optistruct simulation (or increase a number of iterations during optimization in Optistruct)? Regards, Katiya
  6. Спасибо большое, я попробую! Thank you very much, I'll try it.
  7. Выполнила несколько tutorial по топологической оптимизации из этого списка: https://altairhyperworks.com/hwhelp/Altair/2017/help/os/topics/chapter_heads/topology_optimization_tutorials_r.htm Какие туториалы можете посоветовать для лучшего понимания? Для решения своей задачи выполняю аналогичные действия, задаю mindim согласно рекомендуемым в help параметрам. Однако в любом случае получается странная плотность.
  8. Hi, I try to make topology optimization in Optistruct. As the result I got element densities for Design Space in a range of 0.01 - 0.527. In this respect I have the question: how I can exactly fix the element densities value as 0 or 1 and get result without intermediate (fictitious) element densities. Thank you very much!
