  1. I know there is a workaround to this, but this issue has been around for several versions now with now real fix to it (that I know about). If you move the Hypermesh window from one screen to another, or sometimes when you detach the window and it gets resized really small, the main panel (the one at the bottom with the radio buttons) gets resized and keeps pushing the radio buttons and last column to the right. This is a known issue at least since 2014, as shown in this thread. I was wondering if, at least for this problem, there is a way to reload the main panel using TCL-TK, or if there is a possibility to create a script to do this, so that we can run that script whenever the panel goes crazy.
  2. Hello Everyone , any one give me suggestion how to do hexa mesh in this component pleas check and give rply mesh.hm
  3. Dear All, I want to ask about RBE2 application, please see my picture below. I have a simple plate, and I want to give constraint on 2 holes on top, and forces (160kN on both hole or 80kN each hole) on 2 holes on bottom Why my simulation result (stress & deformation) totally different?, because in my opinion, case on the problem 1 and problem 2 are same.... Am I miss something? Best regards, Iron_Man
  4. Whenever I finish exporting a SolverDeck from my tcl gui, and then when I close the tcl GUI, the HyperMesh model becomes completely unresponsive in the Graphics Area after that. The rest of the HyperMesh GUI works perfectly, however I am unable to see the actual geometry / model in the Graphics Area for which I exported the SolverDecks, what could be the issue here ? Any help is appreciated. Thank you.
  5. Hello, I have a query regarding the algorithms followed to form 2d surface mesh. In the help file it is mentioned as advancing front algorithm and sub mapping algorithm, but how these work is not explained . Can anyone share or describe the process.
  6. Hi As part of my thesis at the University, i am working with a simulation dummy from LSTC. I also looked at the tutorial on the positioning of dummies (HM-4640 Dummy Positioning), but unfortunately I could not find this dummy panel on the analysis page. Does this feature require an extension of the license or do I have to make some presets in HyperMesh? Best regards, J.Lauer
  7. Hello, I am analysing coolant flow in a cold plate. I have created 3 volumes namely 1. Fluid volume 2. Volume for cold plate so that in acusolve I will assign it a material 3. Heat source I have applied boundary condition and applied material to volume 2 and fluid properties to volume 1. but I am getting error in final processing. please refer the attachment for the error file and the cold plate design for reference(blue colour is heat source)
  8. How can I use the *evaltclstring function in a globalpage.mac file in hypermesh when the tcl string inside it also has double quotes, such as, *evaltclstring("set t1 [string map {"\n\n" "\n"} $t1]; puts $t1;",0) Any help is appreciated because the above command results in my hypermesh becoming unresponsive on startup. Thank you.
  9. What is meant by card image? Why we are using? Thanks in Advance
  10. How to undo the last command in HyperWorks? Usually, Analysis software wont allow users to undo. There is no undo option. Is there any possibility to undo the last command?
  11. Hi, Is it possible to do Modal analysis for rotor with shaft ( using 3D elements) using following example in optistruct?. or it is applicable for only 1D elements problem?? I have tried . But it is not working for 3D problems OS-1372: Rotor Dynamics of a Hollow Cylindrical Rotor
  12. Dear Community, I have a problem when creating an Optistruct model for freesize optimization including a ply drop-off (PLYDRP) constraint. In particular, I created such a model in Hypermesh 2017 with different design variables (DSIZE). If I export the model in Optistruct format (.fem) and I import it again in Hypermesh 2017, I am not anymore able to see all the DSIZEs but I can see only one of it. I have created a simple model to give you an example. In the file attached, you will find (among the others) four DSIZEs: top, bottom, left, and right. The PLYDRP constraint is activate for all of these design variables. If I export the model to an Optistruct input file (.fem) and I import it again in Hypermesh, I cannot see anymore the four DSIZEs, but only one of them (top) is still there. This happens only if PLYDRP is activated. I would really appreciate if anybody could give me an explanation about this strange behaviour and what to do to avoid it. Thank you in advance, Alessandro plydrop_issue.hm
  13. how to find nearest node in hypermesh. A command or any macro that should search a tolerance of distance like within radius of 30 and then find nodes within that perimeter . lets say, should find nodes adjacent to it.
  14. I'm working on a project on stress analysis of a typical truck chassis frame. I need to mesh the chassis which contains 400 components, mostly nuts, bolts & washers. Can I eliminate all the nuts, bolts & washers for simplified meshing? Will it have an effect on the result? Kindly help as I'm finding it difficult to mesh 400 components. Thank you (:
  15. i am trying to optimize the topology of this tub chassis to get the load paths of the load applied in the form of torsion,braking,acceleration and lateral acceleration. giving minimum element size as 100 i am doing this but it shows this design is not feasible can anyone suggest what is the problem. i have attached .hm file with the question.finally my objective is to minimize the mass of the chassis to convert this tub in space frame. https://www.dropbox.com/s/mzyq7n9dfd9ds5a/topology2.hm this is the link for the .hm file
  16. Hi, Could you provide me some sources or example codes, where I can see the method & commands to write my own menu in Hypermesh? I want to populate the menu list with the macros and access them much easier than under standard User button. Thank you for your advices, Peter
  17. Hello I'm newbie here and I'm still learning tcl/tk and I have problem with bind function in hypermesh. I would like to run a function when the user clicks the left mouse button. For example I want to read position of pointer. I'm using bind function: bind . <Button-1> {myProc} The problem is that it doesn't work when I click mouse button in graphic area. It works fine when I click toolbars or tab areas, but I want to run my function if I click anywhere in HM window. Instead of Button-1 I can use space button in my bind function: bind . <Key-space> {myProc} It works well but it's pointless and you have to use keyboard. Any idea or suggestions how to deal with this? Thanks a lot for help Regards
  18. Hello everyone I have a quite complexe geometry to mesh. For this I have applied 'Check Elements Quality Index', where it shows the quality of the elements. Now I would like to know, if there is a possibility to cut the model, to be able to see the inner contours and how the elements looks there. Then I could have a better overview of the situation and know what to change for the mesh. I thank you in advance for your help!
  19. How to evenly apply a 100N force on a 50mm square surface as a pressure on hypermesh??
