  4. Hello, I am making a sensiviliy study in Hypermesh to see which is the impact of moving one patch some mm in a process of forming composite.I am doing a resine simulation. As the plastic srain of the resin is in function of the elongation of it, I ask myself if the resin has already a pre-tension value before starting he calcul, as its nodes are already deplaced (see image attached). Thank you so much for your answer. Sincerely,
  5. Hi everyone, I´ve encountered a problem when using hypermesh. I have imported and meshed a wing that has the following shape: The problem appears in that sharp line, because when the laminte is created, it intersects in this point. Here is a picture: The cad file is made out of one only surface, so the problem should not be there. In a previous try with the cad made of two faces the same problem appeared, and when simulating I found out the surface was split through that edge. Here the picture. So I am afraid I am going to have the same problem once again with the model of only one surface. The possible sources of error that I can figure out are the model, the messing or the creation of the laminate. This last one actually looks like this: So I would be very grateful if anyone could tell me what things could be made to solve the problem I have.
  6. Hi All, I have a 3D mesh composed of hex elements of a component that looks like a human rib. How can I change the thickness of this 3D mesh in an effecient way? For example, if want the increased the thickness of this component by 10%, what are some to accomplish this? This mesh does not have any surfaces associated with it. So far, I have been translating the nodes of the 3D face elements along a vector to increase the thickness and I am curious if there is a better way. Any help will be appreciated! Cheeres, Sriram
  7. Hello, So I imported a semi-circle geometry from SolidWorks (IGES format) into HyperMesh and ive been trying to carry out topology optimisation on the piece. However, I keep getting the Error code: 2372. I've researched online that it may be PSHELL elements that haven't been deleted but how do I delete these without deleting the mesh? Does it have something to do with the thick line that can be seen in the image or maybe its that node that I can't remove (highlighted by the green ring) [Please look at the image attached] I've been struggling on this for hours, can someone please help?
  8. Hallo Group I am doing Frequecy response analysis following image ie Gobal output control card what does the form field indicate eg real , phase, imagnary, both. Regards Pratik
  9. Good morning to everybody I'm working on ditching bodies in water, modelling it with SPH elements, and the bodies like rigid bodies. I use interface type7, as master i take the body surface, and slave nodes i take the sph elements (nodes); In interface edit panel, i use Istf=1 (just 0 and 1 avaible for sph formulation) and here we came to my need: i have to calculate the interface stifness (with istf=1 STFAC=costant interface sifness), between water and body, because from this depends in a large part the time step, but i don't know how. Should i consider a simple average value between bulk modulus of water and young modulus of body material, or a average weighted value, by a characteristic of entry in water, like entry speed or water height... thanks to all Damir
  10. Hello, When I try to open up hypermesh I get the following error: Error setting up framework: can't read "p_array(Model)":no such element in array while executing "raise $p_array($pagename)" (object"::HM_Framework::NotebookObj1" method "::HM_Framework::TGF_NotebookClass::ActivatePage" body line 3) invoked from within "$nb_obj ActivatePage $activeTabTitle" (procedure "p_InstallNotebookTabs" line 36) invoked from within "p_InstallNotebookTabs" (procedure "::HM_Framework::p_FinishInit" line 22) invoked from within "::HM_Framework::p_FinishInit" I uninstalled and then reinstalled Altair on my computer but the problem still persists. I also tried to remove the hmmenu.st files but that also did not work. What should I do to resolve this problem? Thank you -Eric
  11. Hi, im looking to import a NASTRAN mesh into ANSYS. This can be done directly in workbench, but a lot of information is lost. Specifically I would like to maintain named selections / components - so my strategy was to bring the Nastran bdf into hypermesh, create my groups there, and then export as a cdb before importing it into workbench The problem is whenever I export to cdb I only get nodes in the *.cdb, no elements. I am using Hypermesh 14.0 - anyone have a workaround for this? Thanks ! Tyler
  12. Hello all, How you doing. ? its been a long time since i have asked my question. MY QUESTION: i have .odb files of size 2.7GB , and i am having 16 cases. now i need to send those result files to France. so i planned to use HV TRANS to reduce the ouput file size ( by keeping only the output which i want). i can do that by one by one. but you guys know importing this much size files takes lot of time. so i planned to use the HV TRANS in batch mode. ( some where i studied that batch mode is available ), but i dont how to use it.. 1. Please explain how to import all 16 cases at once in HV TRANS and how to proceed forward in batch mode ? 2. i need to import all 16 files at the same time and i need 16 H3D files.i think this is possible. your opinion pls ? My project delivery date is near by.. so quick suggestion are really appreciated.' thank you.. Regards, Guruganesh NVH
  13. Hi, I am working on DOE of a component in Hypermesh/Optistruct for natural frequency and stiffness (calculated based on nodal displacements). I have developed Tcl code for Automated design changes in Hypermesh which I execute every time for each iteration after changing some values but I need to manually note down responses (Result) in Hyperview. I need a TCL script for Hyperview which after pasting in command window would append to doe.csv or excel: frequency for mode 7, 8 and 9 for subcase 1; and nodal displacements for specific nodes (eg. 30778,7489,76923,77540) for subcase 2, maximum displacement for subcase 3 and subcase 4 in each row. @Livil Lyle
  14. I need to create a macro, which would help me to display the name, material properties and dimensions of a component by clicking/selecting it, moreover if the components contains multiple parts it would help to select only those parts whose Properties tag i wish to display. Any help in this regard is very much appreciated.
  15. Hi, I am attempting to create a lattice structure using CBEAM's. I have created a box geometry and filled it with CBEAM's. This was achieved by solid map meshing, then using the mesh to create CBEAM's. However, I have now applied some BC's and when I run my model I get the message: *** ERROR # 1203 *** in the input data: Vector defined in fields 6 - 8 has zero length. I believe that this has something due to the orientation of by CBEAM's but because I have so many CBEAM's I'm not sure how I would correct the orientation or what to correct the orientation to. I have attached my *.fem file. If someone could have a look I would be very grateful. Laurence Lattice_trial.fem
  16. Hi, I need to create a TCL script that automatically assigns material properties to individual CBEAM elements in a component composed of a large number of CBEAM elements. I am essentially creating a lattice within a component but using CBEAM elements. Does anyone have any advice regarding the script, or how I would go about doing it? Kind Regards, Laurence Maskell
  17. Hi All, How can i get dependent node id of RBE3 elements using tcl commands? Regards, Sanket
  18. hello everyone, How to get independent nodes of rigidlink using tcl commands? Regards, Sanket
  19. Hi, I have a question about boundary condition setting for this work. Assume this is a chassis of truck and fixed. 1) How to set contact between surface and surface? 2) How to fixed? I need to applied load to this plate with 0-100kN in 5 sec of time 3).How to applied? I tried the example but don't understand. I make this with myself don't have adviser. I would like you to help me, Thank you.
  20. Hey guys, I've created a GUI where the user can choose if he wants to apply a pressure load in x-, y- or z-direction by clicking on a button. By clicking on one of the buttons, a variable called "vector" will be created. This variable should later be used in the command that creates the load. Trying to select this variable with $vector on the position that is marked in yellow in the end of the screenshot, nothing happens. Could you somehow help me out with this problem? Kind regards Simon
  21. Hey guys, I'm trying to customize the setting up of simulation, so I'm using the command *createmarkpanel nodes 1 "Choose the relevant nodes for the constraints." to create the constraints. Later on, I use the same command for creating the load. If, for any reasons, I don't want to use this program for creating the constraints and click on proceed without marking any nodes, an error is occurring and the program stops directly. Thus, it's not possible to use the program to mark the nodes for the load afterwards. Is it possible to somehow avoid this error? Here you can find the relevant part of my script for creating the constraints: *createentity loadcols name=loadcol1 *drawlistresetstyle *setvalue loadcols id=1 name="Lagerung" *startnotehistorystate {Created Constraints} *createmarkpanel nodes 1 "Wählen Sie die Knoten der Lagerung aus." *loadcreateonentity_curve nodes 1 3 1 0 0 0 0 0 0 0 0 0 0 0 *endnotehistorystate {Created Constraints} Kind regards, Simon
  22. Hello everyone. I got some pretty strange behaviour of my Solution. 1. The canister seems to float away since the displaced surface at the bottom belongs to the canister 2. The canister itself moves up/down to the plates. In fact it stretches against the plates. general Model: I try to simulate the pressure of the upper plate on the canister, which is limited by the solid lower plate. The Model file is in the attachement. Thanks for your help P.S.: I'm pretty much a beginner in Hypermesh/Optistruct 1mmModelV1.hm
  23. Hey everybody, running the script attached, the following error is occuring: I have absolutely no clue why this is happening. Can you maybe help me out? Kind regards Simon convert_short.tcl
  24. Hello, I want to make a thermal simulation with the solver acusolve in hypermesh. In this simulation i hahave a control volume (water) that flows through a a cold plate i n contact with multiple solids with a heat source. The problem is that when I make the mesh in hypermesh it does not make coincident nodes between txo different volumes, as it does in acuconsole. What should I define te make the nodes in the shared surfaces between different volumes coincident? Thank you
  25. Hey guys! I would like to do a linear thermal analysis. I would like to catch the proper behavior of my system that's why I used constraints in the thickness direction of a thick aluminium plate. The plate should dilate in all direction but the top side of it. How can I apply such constraint which allows the displacement of a node in the positive direction of an axis and obstructs the DoF in the negative direction? Should I use some kind of contact for this purpose? Thank you for your time and your answer in advance! Kind regards, Imre
