Hey Manuel, thanks for all the great videos they are a really fantastic resource to learn. Do you know if it is possible to use non-linear analysis for topology optimization in HyperWorks? I am asking cause it would be a useful feature for displacement driven designs with big deflections. I personally didn't manage to figure out if it is possible so I thought you might know:) Thanks in advance!
Hey :) As far as I know there is no easy way to do a non linear topology optimization as for those topology optimization you need to have derivatives which would be very computationally costly if you would have it in a non linear subcase (each derivative would cause multiple function calls and the validity is limited as it is a linerization) It depends on which non-linearity you are referring to. But the basic saying is - optimization of topology with optistruct - only linear (to my knowledge)
@@ManuelRamsaier Yes, I thought that would not be easy. Thank you for replying, I really appreciate it. Good luck with all of your projects and I am looking forward to watching more of your videos. Cheers
Brilliant video. Do you have a video that details optimisation for a frequency response or modal run in addition to multiple static design cases? Also, do you have a video on geometry export of the optimised structure shape?
both are good topics. There is a video about a frequency response optimization. Geometry export there are multiple options so its difficult to squeze them into one video. But I think I covered OSSmooth in one video. Best regards
Good stuff. Thanks for the video! A small correction, in the opening slide, below the heading, it reads "Part 3: Topology Optimization". I believe it should be part 2, no?
Part 2 was Hyperview which was included in the "Hypermesh FEM Model and Hyperview Tutorial" Video at around 17:29. So my intention was: - Part1: Preprocessing in Hypermesh - Part2: First Run and Post Processing the Analysis - Part3: Topology Optimization Hope this helps :)
Hey Manuel, what if, the error showing *** ERROR # 312 *** In static load case 1 the compliance is negative or large 8.71101e+17. Optimization/buckling analysis cannot be performed. due to possible rigid body mode. FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED). *** SOME ERRORS WERE REPORTED DURING THE RUN, *** PLEASE VERIFY RESULTS AS THEY MAY BE INVALID. what might be the issue here, i followed all the steps, still getting the same error. Can you help me with that?
Thats one of the classic errors - should make a video about it. It means your model is not constraint sufficiently or has loose parts which "fly away" under load.
