  2. @Imoto ご返信遅くなり、申し訳ありません。 ご教授いただきありがとうございます。 追加で質問なのですが、メッシュがCAD表面に載っているか判断するスクリプトやコマンドがありましたら教えていただきたいです。 現在はCADとNODEが関連しているか否かで、CAD表面に載っているかを判断しているのですが 極まれに意図しない箇所に関連づいており、うまく面に載っていない事があり困っています。 よろしくお願いいたします。

  4. シーム溶接 from SOLID CAD内で、SOLIDとしてシーム溶接の位置が明示されている場合は、それを使ってシーム溶接設定することが可能でございます。 動画では、SOLID情報を元にシーム溶接を設定し、その後溶接されていない部品を対象に、automatic contactを使ってボルト部の接続を定義しています。 シーム溶接位置をSOLIDだけでなく、CADのLine情報からも定義できるように、と言うご要望は開発へリクエスト済でございます。 SimSolid_seamweld_fromSolid.mp4
  5. シーム溶接 Group weld シーム溶接については、ソリッドパーツから位置を指定することも可能ですが、シーム溶接設定場所の情報が無い場合、検索して候補を提示し、そこから選択することも可能です(Group weld機能)。 seamweld_groupweld.mp4
  6. スポットウェルドをCADなどから出力した座標値を元に一括定義します。 座標値のcsvフォーマットは添付のものをご参考にしてくださいませ。 また、3枚打ちの場合は追加列が必要となります。3枚打ち.zipをご確認下さいませ。 spotweld.mp4 hat_spot.csv 3枚打ち.zip
  7. Also, Quasi-static solver takes 15 min to solve it; however, explicit solver takes 1 min. What is the reason of this difference ?
  8. Hello, thank you very much for your response. If I have any loading when time is zero, what can I do ?
  9. Yesterday
  10. Sorry, I found the solution. According to the help file, we should import the the material and property into the radioss format file like _0000.rad. Thanks
  11. Dear Edouard, Hello, I was working with Ktex and was wondering to ask your help if it is possible. I ran Ktex woven property so several *.fem file were produced. ( each file size was 2K or 3K!). When I imported the fem file in optistruct, I am not able to see any geometry despite material and its property is shown. Would you please let me know how I can have geometry as well? is there any process that I have not done properly? I also have some plan to do some simulation in Radioss with that meso scale fem file but it seems no format compatible with radioss is produced by running Ktex woven property. Thank you so much for your time and assistance, Nasim
  12. Actually I had the same question. I want to create brick elements, not just surface elements. But 'solid map' doesn't seem to be the right option for that. What was your solution?
  13. Dear Team, for my thesis I have to import models from Solidworks and to assemble them in order to simulate the kinematics of the line trasmission of the primary flight controls. I would like to know how I can assemble models imported in MotionView, as when I import models I can't move them to the right position. I looked for examples, but I didn't find them, so that I ask you if there are tutorials for my case. I apologize for the trivial question, but I am a beginner. I hope you can help me and I thank you in advance.
  14. Last week
  15. Hey Lisa, I saw your model. I think you are running a static linear simulation. I recommend to use Non Linear Static Simulation. And create a new card (NLPARAM) in order to configurate Newton-Raphson scheme for NL anaysis. In contact prop, I would recommend to use S2S discretization. Tell me if you succeed to get what you need (results) Cheers,
  16. Ansys do this type of analysis. Abaqus as well ... For Ansys, please see the following paper : https://www.researchgate.net/publication/237566348_Methods_for_Generating_Rough_Surfaces_in_ANSYS
  17. Your PSOLID property (ID=2) references to material ID=4 which does not exist. So check your materials definition.
  18. Try this code and tell us if it works? *createmarkpanel nodes 1 "Select node" set node1 [hm_getmark nodes 1] *createmarkpanel surfaces 1 "Select surface" set surf_id [hm_getmark surfaces 1] *createmark nodes 1 $node1 *duplicatemark nodes 1 0 hm_createmark nodes 1 -1 set node2 [hm_getmark nodes 1] *createmark nodes 1 $node2 *markprojectnormallytosurface nodes 1 $surf_id set d12 [lindex [split [hm_getdistance nodes $node1 $node2 0] " "] 0] puts [format "Thickness= %0.3f" $d12]
  19. I am getting error sir Let me know where I am getting wrong
  20. Does anyone have .tcl script to measure thickness by projecting nodes from one surface to opposite surface
  21. Anyone have tcl/tk script to measure thickness in hypermesh
  22. Hi, to minimize compliance use minimize internal strain energy response (RTYPE=8). Unfortunately, not all responses are available for Radioss optimization. When the desired response is not directly available from Radioss, it may be calculated using /DRESP2. Or the model could be converted to Optistruct and run explicit dynamic analysis (Radioss simulation in the background). _DRESP1.pdf _DRESP2.pdf
  23. I'm not sure Optistruct (and another FEA softs like Ansys, Abaqus,...) can do contact analyse at microscopic level.
  24. Thanks a lot Mario. I wonder how that happened though. At least, about 80% of the model have been restored
  25. Dear All, Hi, I simulated a laying up process and was thinking to ask you what kind of output I should use to evaluate the angle change in warp and weft direction, fiber reorientation, during laying up ( as shown in Ktex webinar for radome). Any help would be appreciated. Thank you in advance, Cna
  26. I need it to perform simulation with the real contact surface and use the "real" contact stiffness for my application.
  27. Hi, the loading function should be ramped up from zero use Tools>Engine file assistant to define simulation parameters ctrl+F find IMPL/QSTAT = implicit quasistatic second_order_0000.rad
