      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. Hi, From the BCs manager for CLOAD select node option and select the node where the load is to be applied.
  2. Hi Nachiket, Received the files. Will update you soon.
  3. Hi Nachiket, Can you please share the model file through the secure dropbox link (starter, engine file, .h3d and T01), so that we can review the model,
  4. Hi, Please find the document on /MAT/LAW87. Law87.pdf
  5. Hi Gopal, This issue was sorted out and it was regarding the contact. If you face a similar issue please create a separate topic for the same so that we can sort out.
  6. Hi Karthic, It is possible to perform non linear buckling in RADIOSS. Please find the attached tutorial for the same. You can address post buckling application using nonlinear geometry (Implicit) loadcase. You may have to use any of the Arc-Length methods to solve post-buckling analysis, attached is a example which illustrates the same. Buckling.pdf 2_2_snap_roof___implicit.pdf
  7. Hi, You can try with /MAT/LAW87 which is a material law for anisotropic materials. With /MAT/USERij also you can create user material law.
  8. Hi Alessandro, Thank you for notifying on this. User need to switch the global template (accessible in the panel area by pressing "g" on the keyboard) from standard format to long format for entities with Id's more than 8 digits. Please see the attached video file. model.swf
  9. Hi Nachiket, For material removal phenomenon in machining I think modelling with SPH may be helpful. Unfortunately no case studies or tutorials are available now.
  10. Hi, I tried running the same in HW 14.0.230 version and the file ran without any issues. Can you please install this build and try running?, You can download the same from https://connect.altair.com/ The .out file is attached for your reference. PS: Always recommend you to use the latest HyperWorks version, that is HyperWorks 2017 which has a lot of new features. Please go through http://forum.altairhyperworks.com/index.php?/topic/20221- hyperworks-2017- a-platform-for-innovation/ for a short demo. pedersenInverter-81.out
  11. Hi Sumit, In the above shared document it is written that the scaling factor used is 2/sqrt(3.0). Unfortunately we don't have much documents on this currently. Please go through Shell Elements in RADIOSS Theory Manual where this concept is explained.
  12. Hi, It was associated with the property assigned.
  13. Hi, Please try with this model file: model_0000.rad
  14. Hi Sumit, Yes. The minimal normalized height is applicable for shell elements also. Just as a case or example tetra was mentioned in the above post. For RADIOSS, it normally takes the shortest edge to calculate. Please find the attached document on the same. Element_Quality.pdf
  15. Hi, Minimum element lengths are calculated using one of these methods: •The shortest edge of the element. This method is used for non-tetrahedral 3D elements. •The shortest distance from a corner node to its opposing edge (or face, in the case of tetra elements); referred to as "minimal normalized height". • Minimal height, which is the same as minimal normalized height but without a scaling factor. Each check can be set to use a different solver’s check method, or user can set every check to use the same method. Please go through the Help Menu on the same for more description on this topic.
