  1. Hi, I am quite new to the hyperwork and hyperstudy. I am going to do inverse calibration approach to find the hyperelastic material properties for our developed foam material. It means that, I have force-displacement curve from experimental compression test and want to fit the curve with crushable foam model in ABAQUS software. would you please let me know if there is any tutorial that can be helpful as I just installed Hyperwork licence (my organisation, UoA, provided it). Thanks Madie
  2. Hi, I'm using Hyperstudy 2017.2 and Radioss as a solver. I encounter an error when I perform the evaluate step in the DOE approach. It happens that during a run (whatever) the evaluate and extract steps can't finish succesfully, but there aren't errors in the messages box and in the .out file I can read that analysis is already finished with normal termination: in spite of this, the cursor keeps turning and seems to be waiting to finish evaluation. I realized that when it happens, there isn't the .h3d file in the run folder, even if run is completed and all animation A0# are created. I realized also that by finishing the "hvtrans" process from the task manager, or (is the same) Tclsh85t application, hyperstudy concludes the evaluate step, extracts results and goes to the next run. It's a random problem, but it always happens at least once. Thank you all for helping out.
  3. Hello together, I was wondering if there are some kind of tutorials or explanations of the post-processing plots of HyperStudy. I'm trying to understand how ever data set in HyperStudy is been calculated and how every plot is created. Especially the pareto plot, the ordination plot and the linear effects plot are interesting to me. In all the ebooks and overviews I've read hasn't been a complete explanation how HyperStudy creates these plots. Are there some video tutorials or pdf documents where maybe an example is calculated to show which methods are used? It would be a great help if someone has any documents, videos or experiences where I can get this information. I can't really estimate if this is already to deep into learning the program or maybe I just didn't find the right files. I hope somebody can help me out on this topic. Cheers Max
  4. Hi all, This question may be reasonably straight forward to answer (it isn't a trick question at all). When I perform a hyperstudy optimisation study with plate thickness being the variable. Is it possible to dictate what thicknesses I want hyperstudy to investigate? For instance, I have a structure with a plate where I want to know what thickness I can reasonably use without going over a stress limit but I also know that the thicknesses available are 5, 10, 16, 20 mm. How do I get hyperstudy to only look at those values? Cheers Andy
  5. I've set up an optimization study based on tutorial HS-4220 optimization of an impacted beam using my own model for the gauge optimization of crash structure for an ATV. During the both evaluation and optimization, HyperStudy fails to extract the results. Upon looking into the folders it appears that the jobs are not even run in the first place. In order to get the initial results from the setup evaluation, I manually launched the jobs using RADIOSS in the same working directory and they ran fine, generating the required output files. Could someone provide some idea as to why the jobs are not launching correctly through hyperstudy? I would like to run a fairly large optimization study, and manually launching the jobs will take too much time. I have attached the starter, engine, template and HS files. Thank you, Neil 20190723_eATV_HS_OPT.tpl 20190723_eATV_HS_OPT_0000.rad 20190723_eATV_HS_OPT_0001.rad eATV_Gauge_Opt.hstudy
  6. Hello there, I have a problem with running a Study (I've tried on Tutorial file and also on my own model). After evaluation of Nominal run there is no .mrf file created in approach run folder, therefore I'm not able to set the proper response (I'm not able to choose the file for Data Sources). In MotionView analysis output options T've marked to create mrf file, and after MotionView Analysis there is such file created. But unfortunately after HyperStudy nomial run there are just some other files but not the important one Thank you in advance
  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. Hello, We have been running a quit heavy optimisation with hyperstudy using the GRSM algorithm. After about 37 runs, the computer stopped or we had a power cut or something, so we had an abnormal termination of the optimisation. Is there a way to restart the optimisation from where it stopped instead of running the whole thing again? It is a very heavy opt, so it took us a day and a half to run up to iteration 37, and it would be very important for us to just restart from where left. Many thanks in advance.
  9. Hello, I am trying to utilize hyperstudy to optimize a bespoke shell section Beam. Essentially the beam is a hollow I-section but we would like to use hyperstudy to parameterize the thickness. Is this possible? The solver we are using is Optistruct.

  11. 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
  12. Hi, I`m writing my master thesis and I need an help with tutorial HS 4200. I`ve done all the tutorial and I`ve found the parameters shown in the pdf. I`d like to print a comparison plot experimental data vs fitted curve, but I can`t do it. I tried to recover strain and stress in hyperview, but they are different from the experimental stress/strain. Please help me!
  13. Hi, I created a study where I want to analyse the effects of varying plythickness and plyangle of a carbon plate. I defined plythickness and plyangle of every ply as design variable (parameterized file) and then created a DoE. Now i got problems with the response. I dont want to see the composite stress for each Element as itself, but for each ply to have a better overview of the effects. Is there a possibility of filtering my response? By defining my response, I can select the element which is evaluated regarding composite stress. I exactly need the same for selecting a whole ply. Thanks for your support. Regards
  14. Hello, I would like to know how to create a macro (script) using OptiStruct and HyperStudy for dynamic analysis (modal, harmonic and transient) of a free cantilever beam 1D. How to create / import geometry, put materials and properties, meshing, put loads and run the analysis. Thank you
  15. Hello, I want result of frequency response analysis in real and Imaginary form in H3D format. I have specified this in load step and also in Global output control . but still I get output in Phase imaginary form. I am want to use this Vectors Real and Imaginary further in Hyperstudy to do Model updating where I have defined my own criteria. Regards Pratik
  16. Hello, I'm importing a .hm file to the HyperStydy which is a composite model. But I'm not able to import variable other than Material and Moment. Can you point out where I might be going wrong?
  17. Hello, I am trying to use Hyperstudy to perform an inverse analysis to characterize a rubber. But in the tutorial (p367 attached pdf) I used, there is an .xy file required (Stress-Strain data points). How can I switch my type file .txt to .xy please? Thx Regards, Corentin HyperStudy_11.0_Tutorials.pdf
  18. Hi all, I am following the hyperstudy e-book, beam.fem example (Hyperstudy 13.0) but I can't access the expression builder (see attached picture). The nominal run has been written, executed and extracted correctly. What can I do to input the responses I want to investigate? I can't even use the file assistant (probably introduced in the version 14.0?)
  19. Dear all, We are trying to set a HyperStudy simulation. We have a batch process which calls a tcl file and the we read outputs. The problem goes as follows: In the batch process we need to know at which folders we are currently. When Hyperstudy runs the nominal run for instance, it creates folder C:/Users/user1/Desktop/Gen02/approaches/nom_1/run__00001/m_1/ and copies there our .fem file (input) In our batch we are using param %HST_APPROACH_RUN_PATH% to get the path of that folder. But we are getting the parent folder: C:/Users/inasiopo/Desktop/Gen02/approaches/nom_1/run__00001 So .../m_1/ is missing!!!! How can we get the correct path? Hope we explain it in a good way. Many thanks in advance
  20. Hi, I have a model of a plate with many holes that need to be fastened to a beam. I want to make an optimization with Hyperstudy to know where I need to put the bolts to have the minimum stress inside the plate. How can I define my model in Hypermesh, in which Hyperstudy will be able to create all the possible combinations of bolts position for a DOE ? Thank you, Benjamin
  21. Hello I have to optimize bearing length in extrusion process with hyperstudy(I do this with hxsolver (that relateed with hyperstudy directly)) but my supervisor doesnt accept and he wants me that do with hyperstudy and define objective function but I cant define it. how to define response function for obtaining uniform velocity? Thanks alot.
  22. Hi there, I would like to perform a design sweep using Hypermorph and Hyperstudy. The responses I am looking for are the Von Misses stress and/or Strain energy density averaged over a set of elements with a given SID. I have given it a fair attempt, but am stuck. I am only able to select one element at a time when defining responses from file sources. Is there a way to reference all elements in a set, average them and return their mean- whether or not in this order? Thank you and Happy hollidays
  23. hello Group I need to define response from my solver output file (*.h3d) as X axis(frequency) vs Y axis (FRF).. how do i do it in expression builder.. please provide steps for doing it. I tried using freq, frfmag etc from functions tab. was not able to get it. as it expects a vector i dont know how should i refer my frequency and frf response vector values here Regards Pratik
  24. Attached is a Hypermesh deck of a structure whose mass I’m trying to minimize. The structure has a square shaped core covered on the top and bottom by composite facesheets. Shell elements have been used for modeling. The size of the square and the thickness of its wall determine the buckling characteristics of the facesheets. I’ve modeled using a square of side 6mm and its wall thickness is 1.5 mm (shown in the snapshot below). By varying the size of this square and changing the wall thickness, I’m looking to minimse the mass, the constraint being that the buckling factor must always be greater than 1. Could you please help me achieve my objective? Thanks, Kushal Agarwal. square_foam_opti.hm
  25. Hi, I wanted to setup the parametric study for a fan flow analysis at different operating speeds by using HST-AcuSolve. It would be really helpful if it is possible to perform parametric study using hyperstudy. Regards, Vignesh V.
