      Dear Users Our Commercial and Academic users around the world can use these same forums here as before i.e. the Altair Support Forum , Commercial users from India with solver queries can go to the Solver Forum for India Commercial Users , Academic Users from India and AOC India Participants are requested to go to the Forum for India Academic Users and AOC India Participants , We will be tending to all queries in all the forums promptly as before, thank you for your understanding.

  1. I see in your model( .k file without pressure) only one component.Organize 2d elements in to new component.For 2d elements normal are not aligned properly.Correct it by adjust normal option or use 3d element faces.I believe by correcting element normal it should work.
  2. Please try below link to refer requested pdf. https://www.yumpu.com/en/document/view/35065481/1-how-to-create-an-accelerometer-in-hypermesh-for-use-in-ls-dyna
  3. Please find below reply from one of my colleague on similar query wrt to Radioss solver. The Bending and Membrane behavior depends greatly on element's through thickness distribution. The stress distribution across the plate thickness is a linear combination of bending and axial (membrane) stresses so if you have the distribution across the thickness of the plate the axial component is simply the average of stresses on the top and bottom and the bending stresses is the total minus the axial stresses. Through thickness stress distribution becomes very significant when the element undergoes large deformation / rotation or being strained at large plastic strains. These behavoir will be measured / recorded by through thickness integration points The shell element formulation in OptiStruct is based on linear deformation theory and hence do not have through thickness integration points. RADIOSS has the capability of defining through thickness integration points and hence could output Membrane and Bending stress In addition to Top and Bottom layer stresses using the below output commands: /ANIM/SHELL/TENS/MEMB /ANIM/SHELL/TENS/BEND
  4. Could you check same in Model browser. whether it is CAD or FE entity?If possible share hm file to crosscheck same.
  5. As mentioned above i able to import .k file without pressure. I see you have only plate with tetrahedral element & enclose shell elements where you applied pressure. I would recommend you to create pressure with faces option(just pick one face of tet element).No need to have 2d element faces & then export/import .k file.
  6. Hi Rohith, Thanks for sharing files to George.We are working on your query.I too have seen same behaviour with pressure.K file.We will check internally & update you.
  7. Thanks for the update.
  8. It would be nice if you could share model file and screenshot where you want to trim part.
  9. Solid part must have lines.You can use solid edit option to edit soild part.You can create solid from enclose surfaces. Soild : Bounding surfaces
  10. Thanks for the update.Till 13.0 version we had TEMP option listed under linear static,from 14.0 version onward user need to call TEMP card within entity state browser.
  11. Could you share screenshot of display tab?You have shared System tab screenshot. PFA sample of display graphic.
  12. Hi, Just scroll down using slider within entity browser, then you would find TEMP card.I think problem is because of given screenshot. PFA same.
  13. Thanks for the update.I will check internally on this issue & update you soon.
  14. While importing K file does it give any error or warning?Also try import files after deleting setting files.
  15. Could you please let us know the solver used , analysis type & Hyperview version?
