  1. If you have installed Hyperworks help separately ,then in below path you would find the relevant files.PFA same. C:\Program Files\Altair\2019\tutorials\es\nvh nvh.zip
  2. Did you try in HDF5 output format?
  3. Time varying convection Convection coefficients can be specified as time-dependent when a control node (CNTRLND) is specified on CONV card. The control node must be constrained by an SPCD, which is made time dependent by TLOAD1/TLOAD2. The convection coefficient is multiplied by the value from SPCD of control node.
  4. You can refer to below Altair Resource Library with keyword as random. https://altairhyperworks.com/ResourceLibrary.aspx?keywords=random
  5. Could you try this in the OptiStruct latest version 2019.0 or latest point release with 2019.2?
  6. Please refer attached document for complex results in HyperView. Optistruct supports Fatigue in frequency domain: Sine sweep fatigue Random response fatigue For Sine weep fatigue, stress amplitudes and their no. of cycles are determined by sweeping rate and FRF analysis results. Complex Results.pdf
  7. Are you using HyperWorks student Edition 2019?If so , please check the below post for the fix.
  8. 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.
  9. 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
  10. Hello, Is that now or last week?I dont find anything in my outlook.
  11. 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
  12. 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.
  13. 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?
  14. 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.
  15. Constraint and pressure is placed in one collector.Move constraint from pressure loadcollector to Constraint load collector using organize command.
  16. Thermal simulation is only available with RADIOSS explicit.
  17. Please check the load collector with ID = 2.Maybe it is empty, or is missing completely.
  18. Please make sure to install hwsolvers help exe...Optistruct user guide covers detailed information about capabilities and algorithm used for analysis.
  19. Import table from Utility : Table Create
  20. We dont have auto contact recognition during import like SimSolid.Did you try auto contact creation in SimLab ?
  21. New definition concept is for more complex setups & allows more freedom to explore diverse studies in a single session. new_definition_concept.mp4
  22. Please refer to below post and the best practices document pdf shared in last reply.
  23. 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.
  24. Which version of Inspire you are using? Did you try with any other manufacturing constraints. If possible please share the .stmod file.
  25. 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.
