  1. Hej, I am new user of LS-Dyna and hyperview. I have results from Ls-Dyna which i want to post process in Hyper view. I want to plot kinetic energy and internal energy. How can I do that? Which type of file i will impot in hyperview and should i use hyperview graph for that? I have tried to import binary files as well but there is no information about the energies although i can extract energy plots from LS -Prepost. Does any one have an idea how to extract such plots in hyperveiw?
  2. Does 1-plane symmetry is used to define the mid plane of the laminate so that the final stacking sequence will be symmetric around that plane? or this option has no link with laminate stacking sequence and use for defining symmetric plane for the component instead? Any example that demonstrate the use of 1-plane symmetry? Thanks
  3. Thanks but how is it different from the Symmetry option in Laminate panel?
  4. I want to do a free size optimization by considering the laminate as symmetric. Should I do that by specifying symmetric option under laminate panel instead of smear? In that case i only define half of the plies. Is this the right way to obtain symmetric laminate at the end of shuffling optimization? I also heard that there is an option under size optimization called 1-ply symmetry. Is that used for defining symmetric laminate? if yes then how does this option is used? any example or details about it? Can I run the free size optimization as smear and then at the shuffling step end up with a symmetric laminate? What is the best approach to achieve a symmetric laminate at the end ?
  5. Thanks for the info, is there any example/tutorial that use this function or details from manual?
  6. This is not working, since it doesn't remove the ply from the laminate panel and if import this again it gives an error during solver run. Also i dont want to export the file, rather i want to deactivate the ply in the hypermesh and then just press the optistruct to run the solver without considering that inactive ply. Is that possible ?
  7. Hi I would like to turnoff some plies and want to check the affect on the results. How can i turn off it so that it will not include in the laminate and also in the solver? Any quick way to do that?
  8. I have done composite size optimization but wondering if there is any automated tool that can help shape the ply into more manufacturable shapes? Any help in this regard?
  9. I have checked that and it seems like there is no automated tool by which we can prevent getting such small plies? and one has to manually delete them which might be tedious
  10. fairing.hm I am attaching the hm file you can run it as it is and can see if you are also getting the same issue? I slightly modify the tutorial. I am running PCOMPP instead of PCOMPG
  11. I have update it. fem file is attached fairing2_sizing.13.fem
  12. HI, I run a free size composite optimization and i have ended up with more then 400 plies where most of the plies are just one element long. I was thinking why is that and how to deal with it. I also add a mindim = 4*average element size but still i can see plies which are only 1 element long and wide. Any idea why I am getting such plies?
  13. Thanks a lot for clarification but one more clarification. What units should we use here? rev/s or rad/s???? its quite confusing for me at the moment. In the manual it says radians below angular velocity = →ω(radians/unittime)=2πA⋅→R whereas in the same page it also mention that A is a Scale factor of the rotational velocity in revolutions per unit time. so here its saying revolutions. but in one of the post the admin mentioned rev/sec. Can you please clarify this ? https://forum.altair.com/topic/21148-how-to-define-rforce-load/?do=findComment&comment=48833
