  1. Hi, First, make sure you are in Abaqus user profile in HyperMesh. Go to Preferences>> User Profiles>> Abaqus Next, go to 3D page>>Element type>> Select all 1D elements and click update. After this, you can proceed with further modelling.
  2. Hi, The videos in the link below explain 3D mesh generation (tetra & hexa) in detail. It's highly beneficial. There are 2 videos in it. One is theory and the other one is practical. https://altairuniversity.com/getting-started/3d-webinars/
  3. Hi, Before opening HyperMesh software, delete the settings files as explained in the following post: And, change the working directory for the .fem file and then run. If you still face the same issue, share your .hm file if possible.
  4. Hi, To create environment variables in Windows: Right-click the Computer icon and choose Properties, or in Windows Control Panel, choose System. Choose Advanced system settings. On the Advanced tab, click Environment Variables. Click New to create a new environment variable.
  5. Hi Alex, I think you are looking for this:- F10 >> 3D Have a look at the image below.
  6. Hi, The following lines from the attached documents will favour the usage of M54_55 material card. The LS-DYNA MAT54 material model is of interest for large full-scale structural damage simulations because it is a relatively simple material model which requires minimal input parameters. Not only does this reduce the computational requirement of a MAT54 simulation, it also reduces the difficulty and amount of material testing necessary for input parameters. Material 54 uses Chang matrix failure criterion (as Material 22), and material 55 uses the Tsay-Wu criterion for matrix failure. paper-feraboli.pdf open this one crash_feraboli_JAMS May 2011h.pdf
  7. Hi Naresh, I hope the following post will help you in getting output for all the load increments. Also, i am attaching a pdf document which gives information about Intermediate results for Nonlinear static analysis. 1170-OptiStruct-Intermediate-results-for-Nonlinear-static-analysis.pdf
  8. Hi Naresh, Kindly go through the attached post which will give you an idea on how to output every time step result.
  9. Hi, Information about How to change the precision of the value displayed in a note is given in the attached document. Hope it helps. Note_Decimal_value.pdf
  10. Hi Nicole, Kindly look at the attached video which shows how to do morphing. First domain is created, then 'map to geom' option is used.
  11. Hi Nathan, Sytem will resist 1000000 * load input. But, you can't say, that is true for time.
  12. Hi, Yes, it is possible from OptiStruct 2019 onwards. Samples are in the attached documents. T & T 1374 - OptiStruct - Mode Tracking and Rotor Energy from Complex Eigen Value Analysis.pdf 2019-06-07-Altair_OptiStruct2019_New_Feature.pdf
  13. Hi Felipe, A license is only for one machine. So, you need to have a new license for your new laptop. You can request for a new Student Edition license in the following link: https://studentedition.altair.com/
  14. Hi Cappy, Kindly look at the attached video where usage of this feature is shown. I hope this helps.
  15. Hi Natalia, Kindly go through the attached document having guidelines on 3D meshing. HyperMesh_3D_meshing_guidelines.pdf
