  1. Are you using HyperWorks student Edition 2019?If so , please check the below post for the fix.
  2. STATSUB(BUCKLING) can refer to NLSTAT -SMDISP (N2S/S2S contact) but is not allowed to refer a LGDISP subcase. However, linear buckling solution can reference LGDISP-preloaded linear static subcase.
  3. Note: If you are a commercial customer then you could also reach local technical support team.Please check the details below: https://altairhyperworks.com/ClientCenterHWSupportProduct.aspx
  4. Hello, Is that now or last week?I dont find anything in my outlook.
  5. Hi Karth, Sorry for the late reply. We unable to open the file shared by you, as the file uploaded is expired .Could you give a final try by uploading the file in drop box available in my signature
  6. If you are using HyperMesh 2019 or 2019.1.1 latest release, then you could find option to define no of layer under tetramesh parameter and accomplish final terahedral mesh with tetramesh(first subpanel).This should generate layered element on thin region.
  7. Attached is the commonly used formulation for topology optimization as per HyperMesh OptiStruct. Maximize stiffness is already available with Inspire.Compliance is inverse of Stiffness.Can you share screenshot of your model and share the use case or some more information?
  8. I believe you applied load on the nodes.Is that a static load or Dynamic load?If its is static then just count the no of nodes where you applied load....Ensure that load magnitude is uniform or not..If uniform, then just multiply the load magnitude with no of nodes where you apply static load.
  9. Constraint and pressure is placed in one collector.Move constraint from pressure loadcollector to Constraint load collector using organize command.
  10. Thermal simulation is only available with RADIOSS explicit.
  11. Please check the load collector with ID = 2.Maybe it is empty, or is missing completely.
  12. Please make sure to install hwsolvers help exe...Optistruct user guide covers detailed information about capabilities and algorithm used for analysis.
  13. Import table from Utility : Table Create
  14. We dont have auto contact recognition during import like SimSolid.Did you try auto contact creation in SimLab ?
  15. New definition concept is for more complex setups & allows more freedom to explore diverse studies in a single session. new_definition_concept.mp4
  16. Please refer to below post and the best practices document pdf shared in last reply.
  17. Could you directly attach the tutorial pdf which you are referring?Please check whether solver writes .out file or not? If possible share .out and .fem file.
  18. Which version of Inspire you are using? Did you try with any other manufacturing constraints. If possible please share the .stmod file.
  19. Compliance is negative or large, generally this warning comes for modelling error.In your shared file, i see you meshed some 3d enclosed voulme section with 2d mesh/penetraion because of overlap of thickness.
  20. Global Response Search Method (GRSM) & Multi - Objective Genetic Algorithm (MOGA) is used for multiobjective optimization in HyperStudy.You could find more info in online help under optimization method section.
  21. If you are using Student edition, then you may not be able to use the point release. Please check the details below for the research license. https://altairuniversity.com/researcher/success-is-the-ability/
  22. All Optimization disciplines using nonlinear solution with contact only has been supported in OS for a long time.In V2018, nonlinear responses have been added.Contact pressure and contact force from both S2S and N2S contacts can now be used as a response (DRESP1) in optimization formulation. Refer attached model for contact pressure response for shape optimization. Use latest version and refer online help for detailed information. 80_Contpres_model.fem
  23. If you are a commercial customer then please upgrade to HW Desktop 2019.1 (hotfix is 2019.1.1)and for solvers OptiStruct 2019.1 (hotfix is 2019.1.1)
  24. As mentioned above this is available with OptiStruct 2019.1 version. In OptiStruct the MATVE bulk data entry defines the material properties for Viscoelastic materials. MATVE is only supported for Small displacement nonlinear static and transient analysis.& Solid elements both first and second order (CHEXA,CTETRA,CPENTA,CPYRA) are currently supported.Let me know if you need the demo file for same.
  25. Could you please try running this with OptiStruct 2019 or higher version?If possible please share the required .Fem file available in my signature.Files uploaded in dropbox is not working.
