  1. hello, i am new to make scripts. i am trying to do a script to delete empty assemblies and sub assemblies in one action. i need a loop format of script to do this. but i dont know the structure. please help me out.
  2. Hi, how do I convert tria shell elements to quad shell elements of an entire assembly (enclosed for volume creation) ? I want the shell to be quad and I would like to use split quads into trias for my tetra volume generation. But at the moment I have trias in my shell elements which is unfortunate and would like to convert it to quad without beginning from scratch again which is time consuming. thanks.
  3. Hi Experts, I want to automate the assembly creation, I can go in 2 ways. 1. Create an assembly hierarchy in excel file and use the script to implement in my hm file. 2. Create a script to create the assembly hierarchy in hm itself using the user input (selecting the sub-assemblies and components together to form an assembly). Which option would be easier and feasible. I am just a beginner in TCL. Thanks in advance!!
  4. Hi all, I am using Hypermesh of Hyperworks 14.0 to mesh my Geometry and eventually load them into Abaqus (2016) to do the simulation. (Export as .inp Input Deck) I have a rather large assembly with at least 6 components at the detail of the simulation but also want to export the full assembly with >100 components. Now when I meshed all to-be-exported parts and do the export, all the exported parts cannot be loaded as seperate parts but as a combined part. That's not really helpful, as I need to allocate materials, loads etc. pp. My workaround currently to have seperate parts in Abaqus is to export all components seperately. However this brings me all parts as individual models in Abaqus which is not helpful when having >100 components. Also the Abaqus-Tool to seperate the mesh deos not help as there are parts intersecting each other and other parts which get falsely seperated. I also checked with Ansys, same problem, so it seems to be some kind of setting in Hypermesh.. Really appreciate any help and thoughts! Thanks in advance J
  5. Hi Guys, I have UAV tail assembly-assembled from individual components within Catia V5 and imported into Hypermesh. Within Optistruct, I am trying to connect individual components together using connectors (at locations where they interact), however, it fails to connect the components together and I end up with errors. Can you suggest me what is the easiest way to connect components for my type of application? Also, is their any tutorials or videos available for preprocessing of a assembly? Also, here is an image of the assembly that I am working with. Thanks and Regards, Ramon
  6. HI, Can anyone inform how to start meshing the component which i have attached with this post..and give connectivity between two? It is like a cylinder, one component inside another in contact. If i mesh both components separately how will i give connectivity? Is it possible to connect them using 'faces' option? Just give me a basic idea. I have worked on plate structures using mid-surface. i have no idea about solid structures. And how do i use boolean operation to combine them both? Not able to select the components to combine... Can use multi solid option in 3D>solid map to mesh this structure..? Thanks in advance. Please reply.
  7. I'm working on meshing of a truck chassis frame assembly. This assembly contains various components which are repeated in the assembly body. How do I copy meshing of a one component and apply it to other component? (For example, the assembly contains 10 connecting plates. So can I mesh one plate and just copy the meshing to 9 other plates?)
  8. Hello to everyone. A) First of all I would like to know if it's possible to update in SimLab a Creo CAD model (after being modyfied) which has been already opened and meshed in SimLab, by keeping connected the mesh controls setted previously. I'm gonna be clearer: 1- I import a Creo CAD model file (i.e. file name is PIPPO.prt) in SimLab as a part (.prt) or assembly (.asm) by using the command "Import->CAD" 2- I set mesh controls on the model and eventually mesh the component(s) (i.e. I set face mesh control on a face which includes a hole, and a washer mesh control around the hole itself) 3-In the meantime I modify in Creo the CAD model itself (i.e. I change the hole radius) then save by using the same name and overwriting the file (i.e. PIPPO.prt), which is still opened in Sim Lab 4- I import CAD model again (i.e PIPPO.prt) as done in point 1 => now I wish that model geometry could update automatically and that SimLab could recognize connections between the "new" geometry and the old mesh controls, unless big changes (i.e. face mesh control should be still active and linked to the modifyed face, while washer mesh control probably is now missing). Is it possible to do in SimLab? I read in the GUI that you should set the new quotes, when you modify the model in Creo (point 3), as design parameters, so that when you re-import it in SimLab you have to check that "Design Parameters" import option is on and model should update automatically, but I couldn't try this way cause I have another problem: B ) Everytime I choose the option "Import CAD" and I select a .prt or .asm file then Windows says that there is a problem in finding the installation directory (I am not the first person in my company who encounters the same problem, so probably is not due to installation errors). So the only option I have is to use "Import->CAD through traslation" that opens a step (.stp) file auto generated by SimLab, but all of that makes parameters being lost. Did somebody else encountered the same problem? Coming back to A) , and saying that the "design parameters" way could work, does it exist another way which can be even more automatic and simpler? Softwares Assistance once told us to try to assign different colors to different features on the CAD model in Creo to allow SimLab recognize the model during the re-importation. Did somebody ever tried this? Thank you very much for the support
  9. Hi, I need help modeling polar array (rotational symmetry) using system/assembly. When instancing the sub-systems they stay at their original position and orientation. There is an option System translation, but no rotation. The 4 sectors needs to be attached to central polygon as well as to adjacent sector. Is there a way to automatically align subsystems with attachments? polar_array.mdl SECTOR.mdl
  10. Sir, I have a component which is an assembly of 3 different parts. It's a torsional vibration damper consisting of inner mounting part and outer rim both composed of metal which bounded by a rubber part in between them. I want to perform a linear static analysis of the assembly with loads applied on the inner part and constraints applied on outer rim. I have meshed each part with perfect alignment with the adjacent part mesh at the contacting surfaces (so that the each node at the contacting surfaces will be commonly shared by the adjacent parts). The parts are meshed with solid mapping of 2nd order quad elements. Also I have checked that there are no free edges in between the parts contacting region. Being different parts (material), I have applied separate property collector to each one of them. What else should I need do to avoid an unconstrained linear static analysis simulation? I mean how do I convey the software (solver) that the inner and outer parts are bound mutually through the rubber?

  12. Dear All, Can we do assembly level fatigue analysis? I want to do Fatigue analysis of bearing assembly. If yes, Please provide the sample tutorial of fatigue analysis at assembly level.
  13. 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 (:
