  1. Hello, The situation is as follows:- I solve a model. CASE 1: Load Model: .h3d file Load Results: .h3d file I find everything OK. the results are good. Same Model (Solved File) CASE 2: Load Model: .fem file Load Results: .h3d file Results very different from the initial results.(Magnitude of results are very very less). Now i am doing this because i have created a few sets in my model which .h3d file won't read. Then i checked my fem file and it has details of all my element sets created. So i run .fem file along with .h3d file. I get all my sets as created in hypermesh but results would significantly differ. Can anyone help me in resolving this issue. Thank you.
  2. Hi, First time using HyperMesh and I am following a tutorial for topology optimisation. The tutorial I am following is on pages 25-36 in the link provided. When I click OptiStruct, I do not get a message. When I click view.out, I get a message saying: '.out file does not exist.' Where am I going wrong? OptiStruct_11.0_Tutorials_(1).pdf Regards, Laurence
  3. Hi All, I have changed Id of a component in hypermesh and i have a .csv file which contains component's Ids and their thicknesses. Now i want to search component,s id in .csv file and corrosponding thickness value from csv. Can anyone tell me how to do this using tcl? Thanks, Sanket
  4. Hello, How can i see results for a particular component in a big assembly? I know i can just Turn off all the components/elements and show only that particular component to see its results, but i have quite a few iterations and quite a lot of components to carry out this operation. So every time doing this is a painstaking process. So instead i would like to create a few groups before running the analysis like we have elements assigned in Assembly Hierarchy. So while Post-Processing i can directly Turn ON/OFF a particular group to check results. Then saving as the file will also retain the groups for further study and post-processing for other iterations.
  5. hello guys, I am getting a trouble while performing a simulation on HM-CFD-AcuSolve. The simulation in this case is Natural-convection (Acu-3000 in AcuSolve tutorials). when i completed on AcuConsole (following tutorials), the result was OK. But when performing on HM-CFD, the heat from the inner solid does not transfer to the surrounding area (air). So the simulation falied. my version is Engineering solutions 2017.3 and AcuSolve 2018 (downloaded from Altair connect). I tried to check on .INP file generated by both software (AcuConsole and HM-CFD) for the differences but no result. i also add the following command to .INP file (HM-CFD) to make sure the surface transfer heat: wall_function_heat_flux_factor = 1 but nothing work. Does anybody know about this situation? please help. Appreciate. Thank you! P/S: the HM-CFD file is in attached, either the AcuConsole database (.Acs). please view and help me. convection_annulus.hm natural-convection.acs
  6. Hey guys, is there a .tcl-command which shows the maximal node stress of a structure after a simulation? Kind regards and thanks in advance Simon
  7. hello everyone, Can anyone tell me how to convert RBE2 elements to RBE3 elements or reverse too (i.e RBE3 to RBE2). Thanks, Sanket
  8. Hello, Can anyone tell how to create spring elements between two components? Thanks, Sanket
  9. Hi All, I made a mesh using volume tetra and I want to further refine it. How do I use the tetra mesh parameters menu to do this (assuming this is the way to do this)? One of my main goals is to add more layers of elements through the thickness of the whole part, so I thought I could use the "Number of layers" option, and then chose a refinement box that is bigger that my part (i.e. that it encloses my part), and then I thought the next step would be using the tetra remesh menu to remesh everything, but this workflow is not working. I'm probably not using menus within the tretra mesh panel correctly, so what exactly is the workflow of tetra mesh refining other than using proximity and curvature in the volume tetra menu? One aspect that confuses me in the tetra mesh parameters menu is that it only asks for a refinement box: but once I choose my parameters and my refinement box, how to I "apply" this this refinement? Again, my goal is to add more elements through the thickness of my part, which why I specified number of layers = 4. thanks!
  10. Hey guys, I'm looking for a .tcl-command to completely close a program. The program starts with a messagebox where you can choose yes or no. If you select yes, the program runs as it is planned. If you choose no, the whole program should stop. There for I used the exit 2 command. But instead of closing the whole program it only closes the message box and tries to run the code afterwards. Do you have an idea how to fix that problem? This is the relevant part of the code: set starting [tk_messageBox -message "Möchten Sie eine vorhandenes Modell verwenden?" -type yesno -icon question -title "Einladen des Modells"] switch -- $starting { yes { set basedir {C:/} set filetypes {{{Text} {*.fem}} {{Alle} {*}}} set par [tk_getOpenFile \ -initialdir [pwd]\ -title "Startdatei wählen..."\ -filetypes $filetypes ] *feinputwithdata2 "\#optistruct\\optistruct" "$par" 0 0 0 0 0 1 9 1 0 } no { exit 2 } } *createentity mats cardimage=MAT1 name=material1 ... Kind regards, Simon
  11. hello guys, i am doing some AcuSolve tutorials by Engineering Solutions-AcuSolve. I have found some problems with the Transient-heat-transfer while using on HyperMesh-Engineering Solutions. Here they are: 1. I can not restart computing on Engineering Solutions: The mentioned simulation is transient, which require a restart computing base on the previous computed results ( Steady-state). but restart function seemed not intergrated in Engineering solution. 2. Cant assign multiplier function for inlet's temperature: to be more precise, the inlet temperature drop down in few seconds. but this cant be specify in HyperMesh-Engineering solutions. Does anyone know about this issues? Please help. For more informations, please ask. Appreciated!
  12. Hello, I am quite new to hypermesh and I want to create simple solid beam which has a hole and then I want to move the hole. I have built the model in hypermesh and added all the constraints, I have tried morphing but it deformed my meshes while moving the hole by making my beam longer. Would you please help me about which modules I should use? I am currently trying to figure our hyperstudy parametrization
  13. Hi, Can anyone tell me what is tcl command to open mesh panel? Thanks, Sanket
  14. Hey guys, in order to set up a model, I want the user to choose in which degrees of freedom he wants to constrain his model. Is there a .tcl-command that opens a panel automatically where the user can enter specifications, especially the degrees of freedom, for the constraints? Kind regards, Simon
  15. Hey guys, I'm working at a customization problem. During a loop an automesh should be executed when the mesh criterium "aspect ratio" exceeds a specific value. Do you have an idea how I can get access to the aspect ratio values after each iteration? Kind regards Simon
  16. 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
  17. 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
  18. Hey guys, I want to create a .tcl-script, that opens an input mask in HyperMesh where the user can select if he wants to mark elements or nodes (e.g. for force or pressure creation). So by clicking on Nodes he should be able to mark the relevant nodes, by clicking on Elements he should be able to mark the relevant elements. Could you help me out with that problem? Kind regards Simon
  19. Hi, I made a CFD simulation in Hypermesh using AcuSolve. After running the simulation and trying to display the results according to the video posted at the end, I'm required to select a file. However, no .log files are created as on the video and any of the ones created work. Also, unlike on the tutorial, I'm asked to select a Reader, and I don't know which one to use. Can anybody tell me how to make sure .log files (and any others necessary to display results) are created when running the simulation and which Reader to use?
  20. Hi, There are many bolts in assemebly and they are connected by 2 beam elements (there are two elements between one bolt). I want to add one node to that center of it using Tcl if there is no other element is attached to it. How can i do that? Regards, Sanket
  21. Hello Everyone! Recently I have come across with an HM API i.e. "*tangentbetweennodeandline". Syntax for the HM API --- *tangentbetweennodeandline is "node id line id checkpoints lineselected" for using this command it asks us NODE id and a LINE id, also the checkpoint where I generally use "20" for better accuracy. But the only thing which I don't get is what to use in "lineselected" When I use the same option through GUI I was able to select the required line, but when I want to use the above mentioned HM API it is requiring me to hardcode the line number beforehand which I'm not sure of the correct line. So I would be glad if anyone can help me with this specific problem of selection of lineselected. Thanks in advance. Regards, Brahmadev.
  22. Hi, Is there any tutorial deck file available for snap fit analysis using Optistruct implict (OS-E-0170: Snap-Fit analysis (CONSLI vs FINITE)) ? Regards, Arul
  23. Hi everyone, I have problem obtaining the TCL command of auto contact pair finding. My model contains 6 components, I use the Abaqus contact manager to automatically find contact pairs for me. Manually, I can successfully find contact pairs. Since I want to run this process automatically by TCL script, I do the process manually and check out the code added in the command.cmf file. Unfortunately, the code are very long, approximately 50000 lines. Also, the code are about nodes' data and surface set, which is not I am looking for. I am looking for the command that represents the buttons "auto", "components: all", "find", "create". I will show these buttons in the figures attached. By the way, the file: raw.hm is my model. Again, my goal is to get the TCL code for finding contact pairs. Please help me, thanks! raw.hm
  24. Hi, I have been trying to create 2D mesh for a component and later perform tetramesh. i first automesh-ed the critical surface in by size and bias (blue) and remaining surface using surface deviation. However, after performing surface deviation (pink), I'm not getting proper visualization of mesh. How do I resolve?
  25. 空間内にシェル要素による構造物があるモデルで構造ー音響連成解析を行う場合、音響空間のソリッドモデルは図1のようにシェルを挟んで分離させておく必要があります。構造と音響の連成は音響モデルの表面で行われるためです。単にソリッド要素の音響モデルの中にシェル要素の構造モデルが埋め込まれているだけでは連成されませんので注意してください。このようなモデルを作成するのは従来は非常に面倒でしたが、HyperMeshにはdetach from wallという機能が組み込まれており、簡単に分離させることが可能です。HyperMeshリファレンスガイドの抜粋(detach.pdf)のP2にこの機能の概要が記されています。 detach.pdf
