  1. Hey everyone, I have a .bdf file (the solver deck file required for NASTRAN). Hypermesh creates this file by the export process. My work requires that I edit the .bdf text, but also use the graphical features of Hypermesh. I would like to find a way of retaining user-added comments in the .bdf. Let me explain: 1. Create mesh 2. Export as .bdf 3. Comment the .bdf file appropriately -BUT- 4. When I re-import to HM and export, my comments are removed. Is there a way to keep them? Hypermesh will keep comments that are attached to material properties (for example, if I add a comment to a MAT1 card, they will stay with import/export) Thanks for any help!
  2. Hallo, i want to sort the standard parts in my Model with an tcl script. So I want to mirror all standard parts into a Assembly with the Name "300". Further i need sub assemblies for all Screws, Nuts and Washers. For example the structure looks like this: 300 (standard parts) -301 (screws) -303 (nuts) -305 (washer) Furthermore the Comp should exist in the root assembly and in the new assembly. Could anybody help me with this Problem?
  3. Hi all, I'd like to create a script which selects 2d elements of less than 5mm and then displays the element numbers on screen. Any ideas anyone? Much appreciated Andy
  4. Hey there, since a while my Panel is cut off at the side (see screenshot - on the bottom right). Restarting the Programm / PC didn't help. Deactivating Panels in "View" and reactivating neither. Does someone know this problem and could help me with it? Thank's in advance! Cheers
  5. Hello, Is it possible to export Mesh and geometry created in HM to ansys APDL (In .cdb format) Thanks and regards, Bharat
  6. Hello, I would like to tetra mesh my component from a 2D mesh of trias that already exists. The 2D mesh must remain constant as it has a load applied to it that cannot be changed. The problem I am having is that the tetra mesh option 'fixed trias to tetra mesh' produces large size elements in the middle of the model. I would like to constrain the maximum size of the 3D tetra mesh so its does not increase in size in this way. Is this possible? Thank you in advance
  7. Hello, I was wondering how the query commands are used in Hypermesh. For example, if I wanted to use the query command hm_getnodessharedbyothercomps, where would I apply this command in Hypermesh and how could I see the resulting node IDs? Thank you in advance, Alex
  8. good afternoon, colleagues! i'd prepeared model for optistruct, and i tryed to converte it to radioss. convert->optistruct->radioss. but card contact pairs (freeze) haven't rewritten correct. i was trying to remake it again in radioss module, so i can't find "magic bottom"))) Does contact browser (automatic contact) not work in Radioss module? thanks.
  9. We are trying to analyze composite PIPE. When creating a cylinder surface and simply creating Piles and Laminates, it is stacked with the surface as an intermediate plane as shown in the attached image. (Cylindrical surface is white line) For example, are there methods such as stacking layers from the outermost layer toward the inside? (I do not want to change the diameter of the cylinder)
  10. I got a *.dyn file from sheet forming results, how could I to map the thickness property on another mesh file which is continuous in one component.
  11. What is surface normal orientation and how it can be corrected?
  12. Hi. I am analyzing cylindrical pressure vessel with fillet at the inner bottom corner. (Pls see attached picture) During the analysis using Optistruct, it stopped and the error message said that "Element # 2575, element type PENTA" the element was at the tip of the fillet. I know removing the fillet is the one of the best way to gain the quality of elements, but I want to analyze the exact model with fillet. Please tell me how to solve this problem. In above picture, brown is solid element and blue is shell element extracted from the face of the solid element in order to add a inner pressure. I am using HyperWorks ver.13. Thank you.
  13. I am trying to modify a group of Nastran PBAR property groups in Hypermesh via an automated tcl script. I am trying to change the beam sections of all the pbar properties groups I have stored. I have tried using a script with the line as follows (in an iterative manner): *setvalue props id=<some_pbar_prop_id> 3186={beamsects <id_of_new_beam_sect>} While there is no error output, the property card is not updated and the beam section displayed in the GUI is not correct. I am not 100% sure the entity attribute 3186 is correct for pbar beamsections: is there a file or section of the HyperWorks guide listing these id's? I have not been able to find this information. Additionally, I am unsure if the STATUS value needs to be modified in this instance. I have tried the following, also to no avail: *setvalue props id=<some_pbar_prop_id> STATUS=2 3186={beamsects <id_of_new_beam_sect>} or *setvalue props id=<some_pbar_prop_id> 3186={beamsects <id_of_new_beam_sect>} STATUS=2 my beam sections are already defined and are not being generated in the script. Any help resolving this would be greatly appreciated!
  14. Dear AcuSolve Users, Please find the detailed procedure of mapping AcuSolve CFD results through linear interpolation option. It has a python script attached, a pdf document explaining the process to be followed. This Script can be utilized to get all the CFD results like Velocity, Pressure, temperature etc and map it onto other mesh for further analysis. Regards, Kamlesh Script.zip
  15. Hey guys, is there a way to only delete part of a solid? Which means only part of a solids geometry. Unfortunately my model neither has a surface, nor lines. Only solid. If that's not possible, is there way to "reverse transform" a solid into a surface and subsequently a surface into lines? Of Course remodelling the whole model from the very begining starting with the 1D level would work, but I'd like to avoid that. Kind regards, Niclas
  16. Hello, I have a query regarding the generation of core mesh in hypermesh cfd. Why it is necessary to have only tetra core meshing? Is it the requirement for hypermesh or in others also for cfd core must have tetras.
  17. How can I execute a command such as "ls" or "dir" through a tcl script, such that, its output is shown on the tkcon console in HyperMesh ? Any help is appreciated. Thank you.
  18. Hi, I want to simulate the elastic (and further the elasto-plastic) behaviour of arbitrary lattice structures with hyperworks by the use of unit cells. Is there a possibility to apply periodic boundary conditions to simulate unit cells? In addition to that i've tried the Multi-Scale Designer for a simulation like this but there is a major limitation. Within MDS i've to specify matrix and the fiber material but i'm only interested in the behaviour of the fiber material without any influence of the matrix material. I hope someone have a solution regarding this topic ;-) best regards

  20. My second line of toolbar which contain visualization icon with all other icons is missing. I tried the view option but the whole second line is missing. What to do?
  21. Hello Sir, Greetings!!! I have been getting a warning message," Warning: nodes id 14447572 was found more than once in the import file; Resolution: Original id's maintained. Renumbering the database recommended", when I imported the key file, which I had created earlier (LS-Dyna Input File Format). I have a total of 12,000 warnings regarding renumbering. I have tried to renumber the nodes in the file, but the warning still exists. It's not causing any harm to my file, but I would like to know the reason why renumbering of nodes is not working. Hope, to hear from you soon. Thanks & Warm Regards, Akshay S Patil
  22. Hi, I am looking to write a script to place pre-meshed bolts at the bolt holes of an existing bolted flange mesh, an example of which would be below: The bolt hole pattern will not always be a perfect crown, and therefore requires a more general approach Are there any pre-existing tools in Hypermesh that I can use in a tcl script to automate this process? I know hypermesh can find and fill holes, im just wondering if it can find the hole, and tell me the centroid. Or are there any other clever ways for finding the hole centroids based on logically downselecting through tcl scripts? Ultimately the crux is being able to find the centroid of the holes, I can manage the rest of the scripting. If anyone has any ideas that would be greatly appreciated! Thanks Tyler
  23. Is there a simple way by which I could unfreeze the HyperMesh GUI (either a tcl command or through an option in the GUI itself) ? I've been running a long tcl script after the completion of which , the model in the GUI completely freezes. The rest of the HyperMesh GUI works fine but I cannot rotate / shift / select the model / geometry in any way. Any help is appreciated.
  24. Hi, I'm modeling two fastened components in Hypermesh and I'm looking for a way to simulate pretensioned bolts. I've seen there are bolts elements in Hypermesh but i can't understand how to apply a preload. Appreciate your help and suggestions. Thank you in advance.
  25. is there a reason why, when i run optimization via the script in the command file, the hyperworks solver view doesn't pop up? The solver view only shows up when i manually click on run options> OptiStruct
