  1. Hi, I extracted stiffness matrix using DMIG . How to identify the stiffness value of the node and direction and matrix size in .pch file? Pls refer the attached image for reference.
  2. Hello everyone, i just want to know how to see the shear stress in tau_xy and tau_xz direction. I used optistructe as my solver. I only see "max shear" as an option but the result didnt expect as it shoud. the modell is loaded with a lateral force and has a fixed joint.
  3. After analyzing a simply supported beam in hypermesh by optistruct solver I am not being able to view the results in hyperview. I have followed this tutorial : https://connect.altair.com/CP/SA/training/self_paced/os_linear/content/linear_1/PDF/1a_doit.pdf Is it a reader problem or anything else? I am not getting it.
  4. 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
  5. Is there a Hyperview results reader available that will read .pch results files, or a translator that will convert a .pch results file into .h3d or another acceptable file format?
  6. 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
  7. Hi all! I performed a random response in Nastran. I would like to plot the apparent frequency for each element of my model. Is Hyperview capable of this? Besides, I was not able to load random analysis results with multiple subcase in the nastran input file. Is this a limitation of Hyperview?
  8. What is the format file to import in Hyperview NVH Utility for Modal participation Analysis? & What are the cards to activate to extract the output format for modal participation factor analysis from Normal modal analysis / FRF analysis ??
  9. Hello, I am post-processing many sets of results data in Hyperview (20 sets per h3d results file, and multiple h3d files). I have 7 pages with 2-4 Windows per page. I want them all to show the same results set. Right now I need to go into each window and update the results set, and do this 20 times per result, and I have dozens of results. I then need to go through and export photos for each page, and it becomes time consuming. Is there a way to: update ALL windows to the same results set and export ALL plots to PNG files. Also, since I have multiple H3D results files, if there is a way to point all windows to the same file that would be great as well. If I can run this in batch, that would be best, but anything that cuts down on the number of clicks would be helpful since the plots are standard and just need the new results loaded before being exported. I did find the synchronize windows button but that just synchronizes the view, not the results data. I appreciate any help you can give!
  10. Sir, By default, in measures I see dynamic mim/max option to see deformation of nodes having min/max deformation magnitude at the LAST STEP of simulation which can show their deformation values progressively with the simulation steps. However, how can I get the dynamic deformation values of particular node of interest, no matter whether it is having maximum or minimum overall deformation?
  11. Greetings, I'm trying to read data from a node path that I've selected, using the way shown here http://www.altairhyperworks.com/pdfs/tips/1068.pdf I can see the "resolved in" option but I'm unable to change it to my cylindrical local coordinate system. Modeled in hypermesh and solved in abaqus, in Hypermesh I assigned my local csys to all nodes, still no luck. I'll be grateful if someone can help me with this. Thanks in advance.
  12. Hello! I am wondering if there is any way to refresh the result in hyperview while keeping the post-processing style used. Currently, I am saving the session (.mvw) file and reopening it everytime I have new analysis results. If I open the result file, hyperview removes all of the post-processing style I used. It is kind of annoying to reopen the whole session just to update a result from one analysis. I wish there was a refresh result button or an option to keep actual style when opening a result file. I am sure it would be easy to implement this as the "apply style" option easily tranfers a style to a result window. Maybe it exists but I don't know where. Anyone having the same needs? Anyone knows another trick? Thanks in advance!
  13. After performing topology optimization, I don't know the stress contour and displacement contour for the optimized structure ( Last iteration) are for which iso value specifically? Because by changing the iso value the structure modifies, however the stress and displacement contour for the last iteration stay unchanged. In Hyper view there are two sub cases one is design and the other is static analysis. In design sub case we can see all iterations of optimization with respect user defined iso value. In static sub case which my question is about. The static analysis results (displacement and von misses stress) are only available for two iteration (zero iteration and last iteration). I was wondering this plotted displacement and Von Misses stress contour for the last iteration is with respect to what iso value number. Normally for any specified iso value for specific iteration we should have unique stress and displacement contour because by specifying any iso value we are weakening or strengthening the structure. But here in Hyper view for the last iteration there is only one displacement and stress contour and it is not clear for which iso value are these contours! I did attach two pictures from first and last iterations respectively First iteration Last iteration optimized structure (last iteration Iso value=0.5) Optimized structure (last iteration, Iso value 0.2) I want to know the displacement contour (second picture) is for structure with iso value of 0.2 or 0.5 or any other values Thank you in advance
  14. Hello I want to take some values from user so how can I take values from user Like in Hypermesh we use hm_getfloat Is there any command which will serve same purpose in hyperview??
  15. Is it possible to remove Notes from being displayed on a Hyperview window using a tcl command in the console ? I can hide a particular component or set using the GetComponentHandle and SetVisibility commands, however I haven't been able to find a GetNoteHandle or similar command to hide the model info displayed by a Note on the active window.
  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. Hi , Need clarification regarding FRF analysis using Optistruct . What is the need of taking PHASE response in the tutorial - OS-T: 1300 Direct Frequency Response Analysis of a Flat Plate ?? Then what is the use of below responses ??/ Regards, Arul
  18. I'm running a crash simulation in Radioss and I have requested a T file to be written. When I try and load the T file (T01) in hyperview and in hypergraph an error comes up saying it was unable to recognise it. I set the type to 0 default and I also tried 4 because I believe hypergraph can read that. I think data is being written to the file because the file size is fairly large. Any help would be appreciated. _ront_bumper.crashT01
  19. Hı, I'm trying to optimize. But when I showed _lattice_optimze.fem at HyperWorks and _lattice_s1.h3d at hyperview , I see different structure. But I think they are same so I should see same structure. beam_lattice_optimized.fem beam_lattice_s1.h3d
  20. Hi All, I have Abaqus odb files. I want to extract the "Equivalent Plastic Strain" "Max Deflection" "permanent Set" for last subcase and create report in html format. want to write script in hyperview...Please guide me if anyone knows about this... @tinh @Imoto Regards, PD
  21. Hi, My analysis of roll cage is completed but when i click on results hyperview is not showing full model . please help . final year project.h3d final year session.mvw
  22. Hi there, I've run a simulation of the chassis of a car through Optistruct in Hyperview, and there were no errors and everything seemed to run well. However, upon loading into Hyperview, I am unable to view the contour plots for stress/strain/displacement and the four subcases. I am expecting to get a model like Image 1, however am getting image 2. It is as if there are no loads applied to the chassis. If anyone is able to view the model (file attached) and perhaps indicate where I am going wrong it would be greatly appreciated. Cheers Chassis_scaled_newI.hm
  23. Hello, I have a model which includes several surfaces that I need to appear on the postprocessing stage as rigid surfaces. Those aren't meshed since I don't need to resolve for any quantities on them, I just need them to be on my model to be displayed on the results. Here's an image where those surfaces are shown in yellow. Does anyone know how to accomplish that? Thank you in advance.
  24. Hi, Please how can i see the curve ( itérations ) of my objective function in hyperview after a topology optimization ? I THINK THAT WE CAN USE THE FILE .MVW but i dont know how exactly Thank you
  25. Hello, I have a problem when I want to watch my results on Hyperview. Indeed, the numeric value (of the displacement for example) displayed/computed is correct, but during the animation, we can see the displacement does not reach the value (really small displacement animation compare to the value)... I guess it is a problem about the display only. I checked the Scale factor and changed it ('deformed' button), but when I chose beyond around 20, the display diverge/'explode'. Besides, it is not high enough to clearly see the 'real' displacement (value displayed). Can you help me please? Thank you, Corentin
