    Tutorial OS-T 1600

    Hello, i tried to solve the Optistruct OS-T 1600 Tutorial, but after starting the two solvers (optistruct, acusolve) there is a convergence error of acusolve that stops the job: Messages for the job: *** ERROR # 5202 *** Acusolve stops before FSI iteration achieves convergence. *** PROGRAM STOPPED: FATAL ERROR(s) ENCOUNTERED. Does anyone knows the problem? I checked all steps of the tutorial and start it again, but the error still appears. The next step was to change the exchange parameter of acusolve (min/max_stagger_iterations) and optistruct (min/maxEX) to 30. A Simulation of the Tutorial with only 0.02s worked. To simulate the tutorial 0.1s or the whole 1s - as it is described in the Tutorial- still doesn´t work with a value of 100 for max_stagger and MAXEX. Another error appeared: Does anyone has got experience with the tutorial OS-T 1600 and solved it successfull? Thank you very much in advance.
  3. I 've downloaded the captioned tutorial pdf and .fem deck data from Altair Connect. Importing "Thermal.fem" finished sucessfully, but, At Step 5, There is no node numbered "4679". (I searched the node by ID, but HW shows "No change. Total selected 0." ) I would like to know how to find it or if there is specific setting of importing the .fem file. I am using Hypermesh v14. Thanks in advance,

    Skateboard Tutorial

    Hello I'm new to Hyperworks and would like to learn via tutorials, especially Optistuct and Hypermesh for ply and composite analysis and optimisation. I've found a .pdf file and heard about a skateboard tutorial but I can't find the tutorial files anywhere. I'm using Hyperworks 14 (non student edition, I believe). I would be happy if someone could help me with this. Pascal
  5. Hello everyone I would like to do a thermo-mechanical optimization. The thermo-mechanical analysis is already done successfully. Now I was looking for a documentation or tutorial about this sort of topology optimization, but I could not find anything. Does anybody of you have a link or documentation to share, about thermo-mechanical topology optimizations? I thank you very much in advance!

    Tutorial OS-T 1600

    Hello, i tried to solve the Optistruct OS-T 1600 Tutorial, but after starting the two solvers (optistruct, acusolve) there is a convergence error of acusolve that stops the job: Messages for the job: *** ERROR # 5202 *** Acusolve stops before FSI iteration achieves convergence. *** PROGRAM STOPPED: FATAL ERROR(s) ENCOUNTERED. Does anyone knows the problem? I checked all steps of the tutorial and start it again, but the error still appears. The next step was to change the convergence criterio of acusolve (convergence_tolerance) and optistruct (fsi card: FCNVTOL, DCNVTOL) and the exchange parameter of acusolve (min/max_stagger_iterations) and optistruct (min/maxEX), but the error still appears. Does anyone has got experience with the tutorial OS-T 1600 and solved it successfull? Thank you very much in advance.
  7. Hello, i am doing the Optistruct tutorial OS1090 and can't find "heat_transfer_fin.fem" file neither in Hyperworks installation folder nor via Altair connect. I tried by my self but when it comes to select nodes via ID and there is no picture showing the nodes position i am stuck. Please sb. help me finding the tutorials base-files. Regards, Björn
  8. Has anyone used the animation tool successfully? It would be great to incorporate ideation movies into my work. I see there isn't a tutorial on the topic.
  9. Hi there, I was wondering if there are tutorials to help us to learn the post processing softwares. It could be useful to got through some example before using it properly. Thank you.
  10. Hi, I am currently learning how to carry out lattice based optimization on OptiStruct. I have attempted the attached tutorial found elsewhere on the HyperWorks forums, but keep running into the same problem during the Run in OptiStruct? I have tried various edits of the line below the DTPL card line but keep coming across the same error. Any help would be much appreciated? Thanks in advance, Tom Lattice_01.fem Lattice_01.out Lattice Optimisation Tutorial.pdf

    Tutorial file controlarm.fem

    Hello In the tutorial OS-T 3300 Lattice Optimization the file controlarm.fem is needed. I have downloaded the zip file of OptiStruct with this following link I have found: https://altairuniversity.com/model-files-for-student-edition-users-accompaniment-to-the-tutorials-in-help/ But this seems to be the wrong file, as there is no controlarm.fem. Can someone help me to find the right download for this file? I don't have a student edition of HyperMesh/OptiStruct. Thank you in advance for your help!
  12. Hello guys, I tried the tutorial "HS-1545: DOE and Optimization Study with HyperMesh, HyperStudy, and ANSYS CFX" and it worked very well. Now I want to use a .msh file instead of the model.cas file. I thought there should be no problem because it is also a fluent-file. So I created a new study and went through the steps of the setup. When I reached the "evalute" step HS was able to write the Input files. But when HS wanted to execute it shows me always the attached picture. Is it possible to change some terms in the responsible files to avoid this error? Or is it just impossible to use a .msh file?
  13. For thick-walled composite pressure vessels, solid modelling has been added to ESAComp's existing shell analysis module for thin-walled CPVs. The videos in this playlist form a tutorial that describes the modelling approach and workflow in detail. Check-out "Solid CPV Modelling with ESAComp & ComposicaD" now available here -> http://www.altair.com/ResourceLibrary.aspx?translation_id=7541

    OS 2098 error

    Hello, I am trying to run the Optistruct Tutorial OS 2098 with the MBD excavator arm. The analysis works fine, but optimization unfortunately not. Doing everything like in the tutorial, I get errors you can see in the attached output file. Decreasing h_min in the Load_Collector doesn't help. Like it is recommended in line 1062 in the output. But if i decrease h_min to 1e-14, Iteration 0 is running for hours now. So this could not be the right way to solve the tutorial i guess. Is this the only big error? Or are there others I can solve? Would be great to get this tutorial running, because my goal in optistruct is to optimize one part in a MBD, too. Thanks in Advance! os_2098_error.txt

  16. Hello all, I was following the Optistruct tutorial and got stuck at the following step: Step 4: Create temperatures on the inner surface of the pipe 2.From the Analysis page, click constraints. 3.Go to the create subpanel. 4.Make sure the current selection field is set to nodes. 5.Click nodes >> by sets. 6.Select node_temp and click select. 7.Uncheck the box in front of dof1, dof2, dof3, dof4, dof5, and dof6 and verify that the entry fields are set to 0.0. 8.Set load types = to SPC. 9.Click create. This applies the temperature 0.0 on the inside nodes. In the next step, the temperature value will be updated to 60. 10.Click the Card edit icon . 11.Click loads >> by collector. 12.Check the box in front of spc_temp and click select. 13.Click config= and select const. 14.Click type= and select SPC. 15.Click edit. 16.In the field of D, enter 60.0. 17.Click return three times to go back to the Analysis page. Step 16: D is not editable for me. Tried it several times. Loadcollector has no card image (but does not need one, I guess). Your help as always is very appreciated. Merula
