  1. Hi everyone, I am looking for a card image to import node information as text file in a FE model in Optistruct. I have to import residual stresses due to production process, so they are pre-processing information. I found IC card image in GLOBAL_CASE_CONTROL. What about that card? I did not find any description about it. Best regards Martina
  2. I would like to make a script loop script for Yes or no to repeat the action. Please help me out
  3. Hi Guys, I am currently investigating how OptiStruct deals with casting manufacturing constraints. Therefor I use HyperMesh as Pre-Prozessor. As far as I know, the draw options in the DesignVariable sometimes cause walls in parallel to the draw direction. For casting processes this leads to an unideal result, because the casted part won’t get out of the dies easily. Is it possible to specify any constraints concerning draft angles in HyperMesh?
  4. Hello @Rahul Ponginan, I am new to hypermesh. When i was studying theoretically about Finite element analysis, i got to know that the calculations will be made at limited number of nodes and then the result will be interpolated to the entire domain. Can you please tell me that what is "interpolate" in FEA/FEM? I already searched in google and got some theories, but those were unable to understand. Awaiting for your reply. Thanks in an advance. Regards, Saravanan R
  5. Hey guys, I got a question concerning the following model. I want to move all the elements, which are surrounding the holes, into a component. Do you know a command how to mark them? Thanks in advance, Simon
  6. hello, im doing a model correlation between an experimental results stocked in a UNV file, and a numerical simulation run using optistruct while loading both results from the UNV file and the h3d i have a message the said << Node block 2411 or 15 or 781 does not exist >>. this error comes from the UNV file and i don't know how to fix it. thank you for your help!
  7. I'd like to share the seamless integration that Compose with other HyperWorks applications, such as HyperMesh and OptiStruct. In order to expose the Compose function to other HyperWorks applications, we need to register the function. This is done clicking on the right mouse button on Register Function in Compose: After this step, we may now see that the function has been registered under the same mouse click shown above under Show Registered Functions button. Once it is registered, we may now use it inside other HyperWorks softwares, and the function will be available without the need for closing and reopening the application of interest. Example in HyperMesh: Why Compose and HyperMesh? Matrix Browser queries and modifies HyperMesh and HyperView data entities without writing cumbersome TCL coding, along with a Math method developed in Compose. Example in HyperGraph: Why Compose and HyperGraph? Plotting capabilities of HyperGraph are expanded with Compose’s advanced functions and custom procedures developed by the user. Example in HyperView: Why Compose and HyperView? Advanced post-processing or special mathematical approaches may be applied directly on the model. Example in HyperStudy: Add a new output response Define a new expression Use your custom Compose function Why Compose and HyperStudy? User-defined functions to perform design exploration and optimization. Example in OptiStruct: Why Compose and OptiStruct? User-defined functions to perform optimization with DRESP3 card (desired response based on external files). Regards, Roberta
  8. Hi, I got internal programming error with this message. *** INTERNAL PROGRAMMING ERROR *** in file "sparsekit", at location # 1952. ioerr(1) = 0 **** ABORTING RUN DUE TO AN INTERNAL ERROR **** I have attached .out file, can anyone here help me out please CHASSIS_WITHOUT_RIDER_PILIION_FLEX.out
  9. hello, i'm doing a size optimization in order to match the drequencies targets for the first 10 modes. so i defined my design variable wich is the PBUSH stifness k1..k6 and as and objective is the MIn using DSYSID (iwth all the 10 first frequancies and the targets) but some how i don't have the right results thats i want i have in my model DESVAR refered to stifness of PBUSH DVPREL1 DRESP1 MIN WITH a DSYSID everythings is well defined i don"t if there something else to add to my optimization to work
  10. 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
  11. I'd like to share the nice and slick synergy Compose has with Matrix Browser, a feature in HyperMesh to handle model data in table format. This is the typical use case when the model data will lead the process and Compose will play as the Math/Automation engine. Let’s assume that we have the model ExampleRib.fem (attached) and that we would like to get the central coordinates X, Y and Z of a few elements: In this example, I’d like to calculate the central distance of these elements to the point (0,0,0), which would be simply the square root of x²+y²+z². For that, I created a custom Compose function distZero (also attached): Which will receive as inputs from HyperMesh the coordinates X, Y and Z that I queried with Matrix Browser. In order to expose the Compose function to other HyperWorks applications, we need to register the function. This is done clicking on the right mouse button on Register Function in Compose: After this step, we may now see that the function has been registered under the same mouse click shown above under Show Registered Functions button. Once it is registered, we may now use it inside HyperMesh + Matrix Browser: The function will be available without the need for closing HyperMesh and reopening. Then we give the columns that will serve as arguments: And it's done! The custom Compose function calculated everything and the results are shown in a new column: Regards, Roberta ExampleRib.fem distZero.oml
  12. 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
  13. 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.
  14. Is there a way to put notes in HyperMesh, the same way as its done in HyperView. Please help in doing the same.
  15. hello, i want to define a anistripic material in optistruct and i don't know what card image should be used for such a material. thanks
  16. Hi, I have a model that contains many 1D beams. In hypermesh, it is possible to view 1d elements as "1D traditional and detailed element representation". Is it possible to do this in Hyperview? Kind Regards, Laurence
  17. Hi, I have a hm file (or fem) and a TCL script. I want to run my hm file with the tcl script in a loop and output the results so I can analyse all of them. How do I achieve this? Kind Regards, Laurence
  18. 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
  19. Hi, I have a structure that is composed of many CBEAM elements, all of these CBEAM elements are under one property and one material. I need each of the individual CBEAM elements to have its own property and material. Is there a way to automate this. I have ~9000 beams. I could lower the number of beams to something manageable so I could organize them individually but this is not ideal. The end goal is to be able to alter the material properties of individual CBEAM's, E1 for example, simulating progressive damage with progressive lattice failure. Can anyone help? I have attached my .fem and hm for your visualisation. Kind Regards, Laurence clevis2.0run.fem clevis2.0run.hm
  20. Hi All, what is closet node and how to use it for drag command using tcl commands? Regards, Sanket
  21. Hello All, I want to delete elements on YZ plane. How can i delete elements using tcl commands? Regards, Sanket
  22. Hello, I am new to acusolve ! I would like to model a simple heated plate case, I meshed the volume of air and the plate already. However when I try to export to AcuConsole some errors occur just as shown below : Can somebody tell me what I did wrong please ? Thanks ! heated_plate.hm
  23. Hi, I have written a script in TCL that changes the material properties using an automatic number generator. The script works when I write it into the console, (The interpreter at the bottom of the page, not sure of the correct name). But when I run the script using the run TCL script button nothing happens. I have attached the script. It changes the material properties of a MAT9ORT card. Can someone take a look at my script and give me some advice on how it can be changed to run correctly. I have also attached my hm file for which I am attempting to change the material properties. Kind Regards, Laurence Maskell YMbeamchanger.tcl clevis2.0run.hm
  24. Hello everybody, I have some problems with stress initialization simulation of solid element: I'd like to do a simulation made of two step where the second step shall take into account strain and stress of first step. I have try to use \inista but there is something wrong because in second step, at first frame, the part have no stress. The procedure I have used is: - STEP I: /IOFLAG - eport solver deck from HyperView for the deformed shape - STEP II: /INISTA In attach the file .rad of simulation. Thank you in advance for your help!

  25. 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
