  1. Hello, i am using HyperView 2019.1. When i try to visualise the displacements in my simulation via "Contour -> Result type: Displacement -> Apply" i can't see the corresponding legend. The same problem applies when visualising the stress or strain. In preceding versions of HyperView this was not a problem. So i hope someone can help me "turn on" the legend. Thanks!
  2. What is the way to find out assembly name of a component from element id or component id in hyperview?
  3. Hello I have 13 pages of modal simulation results. Is there any single click option to export all pages as gif files. Currently I am saving each page manually. Thanks
  4. Hello all I would like to find an way to link hypermesh to analytical calculation. For analytical calculation, I think the software will be excel or hyperstudy. Summaries the steps; 1-I would like create a section cut with selected nodes and elements and get the cross section properties ( which is available aerospace section cut command) . 2- Read the FBD forces on that nodes and elements. 3- Do some math with the crossection properties and FBD forces. Which steps and softwares required for this process? What are your recommendations? Best Regards
  5. Dear, I did a sweep calculation for a Degas Bottle, the frequency range is from 15Hz to 100Hz, acceleration level is 3g, when I got the response stress after the model frequency simulation, I outputted the stress tensor of the most critical element, but I found there are 12 stress tensor in the pch file, so how the hyperview use these tensor to get the plot stress? I could not find the way. Meanwhile, how the Optistruct calculate the damage based on the response stress, I mean how to calculate the cycles at interested frequency, I know the help document, but it doesn't tell too much. Thanks a lot! 20191202_GWM_B30_Degas_Bottle_LT_V5_Opt.pch
  6. Hello all. I know there is a very good tutorial on the subject (https://www.youtube.com/watch?v=236ofmwz1X4) however I would like to share my latest experience when comparing stress results obtained from two different solvers i.e. MSC NASTRAN and Optistruct. By default NASTRAN calculates stress using the command: STRESS(PLOT,SORT1,REAL,VONMISES,BILIN)=ALL, meaning that (if you neglect the other terms) a bilinear extrapolation is used to get the stresses from the element's centroid to the nodes. Since optistruct/RADIOSS calculates stress at the element's centroid by default, I supposed that the equivalent command in the .fem input file for optistruct would be: STRESS(SORT1,H3D,REAL,ALL,BILIN) = YES (I have replaced "VONMISES" with "ALL" to have all stresses in my output) and performed two examples of simple static analyses: one with shell elements: the well known hole in plate and another with a bracket meshed with solid elements (4 noded tetras). In both cases the results from MSC NASTRAN and Optistruct were identical, as long as in Hyperview I activated the option "use corner data" (participation of element to the node). Without "corner data" activation the difference in VM stress between NASTRAN and Optistruct for the hole in plate problem was 175 MPa (NASTRAN) to 157 MPa (Optistruct). Now: I performed an analysis of a 3d bolted connection (two plates connected with a 3d bolt) with bolt pretension as a first step and a tensile force acting on the top plate of the connection as the second step. Obviously, this problem involved contact between the plates and the bolt. The analysis converged and the results were correct since I knew from published results (and NASTRAN) that max. stress should be approx. 80 MPa. I received the same results with optistruct, but without the "use corner data" activated, although I have used the command described before for stress. If I activate the corner data in Hyperview, then my stresses almost double in magnitude (156 MPa). So, this contradicts with what I have found with my previous tests (hole in plate and 3d bracket). Does it have to do with the "contact"? Thank you in advance for your reply.
  7. Hello, Is possible use Hyperview to export/convert results to an Abaqus ODB file?
  8. I made a normal modes analysis and now with Hyperview i'm trying to get the data I need. I already got the eigenvectors (X,Y,Z) for each of the modes using the Matrix Browser. Nevertheless when I get those result I don't get the natural frequency (eigenfrequency) related to that specific eigenvectors. As you see in the picture below, the frequency doesn't appear (only that those data is related to "sel1"). How could I make the eigenfrequency to appear there so ones I postprocess the results I can get access to that data? Thanks in advance Sergio
  9. I attempt to go through Toplology Optimisation with relative displacement (in x, y, z) as constraints and loadcases. SoI need to select all the nodes displacements at certain cross sections, where there is the only path transfering force to design area. I am new to optistruct and hyperview, I just noticed it is possible to select cross section and read also output every nodes' displacement in Excel. My question is, does it work in this way? and if yes, How should I input these data (should be more than hundred nodes) into Optistruct as an easy way? A tutorial would be so appreciated! Cheers!
  10. Hello, I have performed a transient thermal simulation with OptiStruct. I want to get the surface average value of temperatures in a surface for all the time steps, but I don´t know how to get it. Do you have any idea of how to do it in HyperView? Thank you very much Juan Iradier
  11. Hi How to output the result file in h3d format what the output fields i have to use to get rhe output in h3d format
  12. Hi! I wanna model the rotation of a gear (wheel) with a preload in the pinion. I asume the preload is modeled with a moment but, how do I model the rotation? And which analysis type should I choose? (I don't want a quasi-static one). Some analysis don't let me include a LOAD. Thanks in advance!

  15. Hi, Is there a query command to identify elements attached to nodes in Hyperview? I can identify nodes attached to elements by using element.connectivity. There isn't such query available for nodes. Thanks, Roshan
  16. Hi, I am creating a script where I want to orient the model such that I can clearly view the interested node and capture a zoomed-in image. So far, I am able to set the desired orientation. But, I am unable to zoom exactly at the interested node. Is there any way I can achieve this? Thanks, Roshan
  17. Hello, After completing the optimization, there are 50 runs due to the algorithm and inside all of the runs there are s1.h3d files where I can see the results of each evaluation and I can add results manually in hyperview but for more evaluations it is quite a hard job to do. So I wanted to ask if there is an easier or automatized way to see all s1.h3d files of runs together in hyperview? thank you
  18. Hi, Is there any command available to get the name of steps in Hyperview? I got number of steps by using the command "hwIAnimator GetNumberOfSteps". From this or any other way can I get the step names? Thanks in advance for considering my request. Regards Mohammed
  19. hello everyone, i want to do an optimization in order to increase the correlation between experimantal results and numerical ones, using MAC cretria, my design variables are the stifness of the damping springs. my size optimization is well set it works but i don't know how can i connect the expermental result that i have in an .UNV file and the numerical results. to say to optistruct i want to increase the mac between the two. i know that i have to use the parameter TRAKMETH MODETRACK MFILTER. but i don't know the right steps to operate this one. if you have some ideas i will be greatful thanks.
  20. Hi, What is the command for finding hyperview version? Is there any command similar to hm_info in Hyperview? Thanks Mohammed
  21. 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
  22. Can some would suggest me script for read and write all the subcase names and their respective ids, for now to get all subcases names, I am using- hwi GetSessionHandle mySessionName mySessionName GetDataFileHandle myDataFile $op2File set subcase_list [myDataFile GetSubcaseList] puts "subcase_list $subcase_list" can some suggest script or code to find all Subcases ids with minimal changes in above.
  23. 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
  24. 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
  25. Is there a way to put notes in HyperMesh, the same way as its done in HyperView. Please help in doing the same.
