  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. Hey all, I am a bit confused right now. I did some exercise with hyperview tcl. I set up a real simple script: # Hyperview Exercise1 hwi OpenStack hwi GetSessionHandle session1 session1 GetProjectHandle project1 project GetPageHandle page1 1 page1 GetWindowHandle win1 1 win1 SetClientType animation hwi CloseStack When running the script multiple times it says several times: session1: object with this name already exists. I thought, wit hhwi CloseStack all handles would get released which is not the case? Someone seeing the same behaviour with those lines running 2 times? Thanks in advance and best regards, Merula
  5. Dear sir, I am doing Head Impact on ip and plotted the acceleration curves in hyper graph. But i couldnt extract the HIC value from the vehicle safety preferences tool as it is showing rectangular curves as shown in the attachment, can i know how can i get hic values from the curve perfecly in hypergraph?
  6. 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
  7. 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
  8. 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.
  9. Hello, Is possible use Hyperview to export/convert results to an Abaqus ODB file?
  10. 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
  11. 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.
  12. I have a results file with 120 subcases. Each subcase has its own contour plot and results. I want to retrieve the max displacement for each subcase and write it to a file without having to view each subcase. Ideally, I would like the legend value of the displacement to be "fixed" not "scientific". I've written a couple TCL scripts for Hypermesh, and am familiar with the puts for writing to the file, but have no idea what any of the commands are for the hyperview tcl.
  13. Hi, I wish to create a tcl script to record the steps I perform in Hyperview, something like a MACRO. However I see that it Hyperview does not offer an option to do so like in Hypermesh. Can anyone help me with that?
  14. Dear Hyperview users, i'm doing a static analysis on a fortran code and i want to visualize results graphically using Hyperview, the problem is that the structure info are in .'"dat" format so i need to transform it into hwascii file in order to import in Hyperview; is there any software that can do this job ?
  15. hey! can someone teach me how to apply load to this engine bracket by using hyperworks. i have problem with attach the 42 degree load and torsional load for the bracket. you can see the load type from the diagram. i also attach the iges file of the bracket for your reference. My target is to reduce atleast 20% of its weight. please contact me if u guys can help me. i really need to know how to put the load. thank you. original.igs
  16. Hello, Can someone please tell me if there is a way to view the deformation and displacement of a section of a model on hyperview? I want to see the deformation in a certain section of a cylinder. Thank you in advanced Kind regards
  17. Hi! I am trying to simulate, using hypermesh (optistruct), a 3 point bending test of a composite sandwich panel made of carbon fiber and aramid honeycomb. I have modelled the core using PSOLID property and MAT9ORT material and the skin where modelled using the tool "find faces", and then creating four CFK plies that form a laminate which is associated to the property PCOMPP that the skins have. I used MAT8 to define CFK plies. The Optistruct solver doesn't output any errors at all; however, when visualising the deformed shape, it represents an absolutely wrong and wierd shape for the sandwich panel where the supports are as shown in the attached picture (right and left side of the photo). I've tried to model it several times and even change some properties in case there was material failure in such points, but didn't work. I need help as soon as possible. Thank you!
  18. Hi, I´ve done a structural study and I want to send the results to a partner. Is possible to export a 3D view of it in a format that isn´t necesary have hyperview for open it (something like edrawings in solidworks) or if its possible export a step o similar format with results map attached. Thanks in advance
  19. Hello hyperview users, I am new to hyperview and I want to create a template that could export images on a separate file (.txt .ppt etc..). For the moment I have create a template that generates 8 windows, and I use the copy/past tool on each window to export images. Any suggestion to use improve my template and export every windows ? Pierre
  20. Hi, I have a saved templete which generates a graph between stress vs strain for a given element id i.e. E181115 (in my case). The graph can be seen in attchments. #Now i want to change the element id or write a tcl code in such a way that it should ask me to enter the element id before running my template. I am very new to hyperview and have no idea how to covert .tpl to .tcl, Any answers, suggestions could be very much helpful. I am also attching my .tpl file (for understanding) Thanks in advance Agassi e181115.tpl
  21. Hello So I have script to save perticular view in hyperview window and can be retrieved later, but it only retrieves view irrespective of display status of different components Now I want to extend this script further so that it will save the view along with the ids of component displayed in window (like hypermesh save view and retrieve) any suggestion on how can I do this?
  22. Hello everyone I am new to hyperview scripting I dont have much Idea about commands used I have gone through previous posts Also trying to read Template file and session file Still I will appreciate If everyone attach there own script in reply. It will accelerate process of learning Beginner like me can refer to those files and create a new script with help of those commands Thank you
  23. Hi, Is there a way using tcl commands by which I could split the HyperView page window layout into more than 4 parts ?

    Opening model in HyperView

    Hi, I used the RADIOSS version 12 software for a simulation. I tried reading the results on the downloadable student version but to no avail. It asked me "select model reader" I tried the possibilities without results. : Thanks, Pierre FLANDIN
  25. Is it possible to run a cmd command such as "dir" using exec or another method in tcl and store the output of that command in a string without opening up the actual cmd terminal ? Thank you.
