  1. I'm currently trying out SimSolid for various types of problems and have found it to be very impressive! I had a question about modelling a spherical joint/ connector. As far as I know, SimSolid currently provides an option of modelling a pin joint between parts and a hinged/spherical support with the ground, but does not provide an option to model a spherical joint. An option to create a spring between 2 parts with translation and rotational stiffness (equivalent to the CBUSH element in OptiStruct) or a ready spherical connector would be great! Is this feature planned to be added in a future release? I'm currently trying to do this by physically modelling a ball and socket geometry and defining a separating/closing contact with very low coefficient of friction between the surfaces. The non-linear solution takes multiple passes to solve (even for a small ball-socket trial problem) with mixed results. Would really appreciate it if someone could provide an insight on a way to do this.
  2. Hi, I hope I do not bother anyone with questions to which answers might be obvious to advanced users. Using Hyperworks 11, I'd like to create a simple adhesive contact in Hypermesh between two solid compontents, hex mesh. The tutorial HM-3410: "Creating Area Connectors" only treats 2D-elements and doesn't work the same way for 3D-elements. Could anyone give me a short hint how to "glue" two compontens together, please? I would appreciate it very much. Have a nice day Hampel
  3. Hello All, i am looking for a way to extract connectors from different types of link entities in my model. The question right now concerns an adhesive sealing for the windscreen, which consists of a hexa body, rbe2-elements from the hexa nodes normal to the face to be linked and rbe3 to connect the rbe2-elements to the face elements' corner nodes. See the attached picture. I want to extract this via fe absorb as a seam connector but so far it is not working (absorb as spot is also not working). Has anybody some idea or maybe some customization info on how to get this done? The model is a Nastran model and im using Optisruct UI in HM Thanks in advance!
  4. Hey everyone, sometimes I have to create area connectors (for adhesive) on sheet metal parts. Those parts mostly have flanges, an area which is parallel to an corresponding area of another part. The two parts are connected at their two flanges. I wonder how can I detect this flanges automatically and create area connectors at those flanges efficiently? For Spotwelds there is the functionality "Autopitch", which detects flanges and creates spotweld connectors according to parameters. Is there something similar for area connectors? Does someone know an efficient way of creating area connectors?
  5. Hi, I tried to connect a 1D Bar (comp id 1) element with a 2D Shell. But when I create a connector Spot weld I always get the error “failed: Link entity 1 (comp id 1) does not have a projection”. Is it not possible to connect a Bar element with a Shell element using connectors? Kind Regards, Simon
  6. Hi all, i am missing some reference on the taperd-T-seam-connector in HM (LS-Dyna profile) in the help documentation. there are three types with different parameter sets but i need some description of how they influence the elements geometry. Could you help ? ?
  7. Hi all, I have in my model 2 components with perfect interface between them. When i run my analysis (with force boundaries condition in one of the component), i see that the load is not transfer to the second component because of the interface between the 2 components. My question is in this case what kind of connector do i have to use to get perfect connection between interface ? is that possible to merge this 2 components in a same component so that i can ovoid the interface : how to do it in hypermesh ? Thanks a lot for your help.
  8. 指定した直系以下の穴を見つけて、穴同士のペアが指定距離以内であれば、そこにボルトコネクター(締結ペアと位置情報)を作ることができます。 ※HyperWorksDesktop2017.2.3以上のアップデートが必要です。 手順は、下記ビデオをご確認下さい。 HoleDetection.mp4
  9. Hi, what is the main reason for unrealization of adhesive connectors? also is it possible to project the mesh from one component to an adjacent component?
  10. Hi, I'm currently experimenting with different connection types to simulate adhesive bonds. I want to find the best way to analyze large scale bonded shell models. So far I've been examined different options for area connectors, such as: shell gap, mid thickness, etc. The problem I have is that when I increase the adhesive thickness I get some incorrect results. Up to 3 mm in thickness, all the results seem acceptable, but with 5 mm and 10 mm thickness it looks false. More details: I use Optistruct, and running a Linear Static analysis The adhesive layer seems too rigid, although I use the real parameters of the glue. It seems like the glue is trying to maintain its position (perpendicular) to the sheet, and isn't deforming enough. My question is: is there any rule regarding the range that a connector type can be used in? (For example: area connector in shell gap mode is good for adhesive layers in the 1-3 mm range.) Or in other words, is there a limit thickness where adhesive area connectors can't be used anymore? I attached the model I was using. Also, what modelling method can you suggest to analyse large scale shell models with adhesives (for example: a boat)? Thanks, Sebo kiskocka_slp_9.hm
  11. Two bodies are connected by means of bearing (upper race and lower race bolted to respective bodies). Detailed analysis (ignore bearing model) is not required. What type of connections could be given between two components? Can we assume a block instead of bearing, and give what type of connections?
  12. Hello, i am actually working on a model in which i want to connect two solids with a bolt. Can anyone explain me what is the difference between the different types available. I think i have to use the type = hinge because ist seems like this type represents a rotatin bolt. If someone got a list or so what showing the diffeences it would be very helpfull to me. Tank you. Jonas
  13. おせわになっております。 現在、強度解析と振動解析でボルト締結がRIGIDを再現していますがボルト周りの応力が大きく発生しました。RIGIDの方法以外、他の再現方法を教えていただきます。 サンプルモデルがあれば助かります。よろしくお願いします。
  14. Hi, I would like to connect the "bracing_1" to "bracing_2" and connect the "bracing_2" to "flange" component, representing a weld, without remeshing any of them. I've tried spot, seam and area connectors with various options but none of them worked, after running the simulation, the connected components weren't constrained together. What is the most simple method to connect components with non-connecting mesh? Thank you aecyd tubes.zip
  15. リアライズされていない(梁要素が作成されていない)重複コネクターであれば、 ◎1Dページ⇒「connectors」⇒「quality」⇒◎connectors(unrealizezd)で、 青色の「preview duplicates」をクリックすると重複コネクターの検出(ハイライト)、 緑色の「remove duplicates」をクリックすると検出されたコネクターの削除を行うことができます。
  16. I use Feko version 14.0.432 and try to design SMA connector. But I don't know how to add source port. Please advise.
  17. Hello, I am using 3D tet elements to model a variety of bolted flange plates. I would like to use simplified 1D beam elements as bolts, with RBE2 to connect to each part. Is there a way to use the connector panel to help make this easier? I cannot seem to figure out how to do it for 3D meshes. Also, I have not actually meshed the holes as I am trying to reduce geometric complexity - I have just included a circular "washer" surface for the RBE2 elements to grab on to. My solver is Optistruct. Thank you, Justin
