  1. GPFORCE is not necessary for one step TPA, and pfpath can deal with this internally. In HyperView ,ensure that the NVH Utilities are loaded from the Preferences menu.This should help you to get the Input Force, Transfer Function and Point Mobility. PFA material for post processing using NVH utilities. TPA_Sample_decks_ELForce.zip
  2. This is dynamic analysis (time domain)problem.You could use TLOAD2 card to define the equation
  3. During the study setup ,set the input variable modes option to discrete. Refer attached HyperStudy tutorial. HS-4230_Optimization_Study_with_Discrete_Variables.pdf
  4. https://forum.altair.com/topic/36286-superficial-stresses-on-3d-castings-membrane-elements/
  5. If you are looking for surface stress then in V2017.2, surface stresses can be requested without having to model additional membrane elements.Please attached attached material for same. Surface_stresses_without_membrane.zip
  6. Refer below video from Altair Learning library for material orientation https://altairuniversity.com/learning-library/checking-element-normals-and-assigning-material-orientation-using-hypermesh/
  7. Please refer to free ebook on nonlinear analysis using OptiStruct.Online help covers several example/tutorial and Verification problem. https://altairuniversity.com/free-ebook-introduction-to-nonlinear-finite-element-analysis-using-optistruct/ OptiStruct nonlinear learning center
  8. Please refer attached document for contact penalty formulation in OptiStruct.For more information refer OptiStruct online help and free eBook on OptiStruct nonlinear analysis using below link. https://altairuniversity.com/free-ebook-introduction-to-nonlinear-finite-element-analysis-using-optistruct/ Contact Penalty Formulation.pdf
  9. Which version of OptiStruct you are using? Could you please share the .out file of the run.
  10. Try with Derived result with advanced result math template in Hyperview.
  11. To disable the unit scaling using the following Preferences Statement: *BeginPlotDefaults() *EnableUnitScaling(false)
  12. This is the known issue reported in HyperView 2019.1 version which should get resolved in upcoming hotfix. Temporary solutions are provided below : Download the attachment library files and replace the old ones in installation folders: Windows: C:\Altair\2019.1\io\result_readers\bin\win64\acusolve_hv.dll Linux: /scratch1/Applications/HyperWorks/2019.1/altair/io/result_readers/bin/linux64/acusolve_hv.so acusolve_hv.dll acusolve_hv.so
  13. Please refer attached document for FFT using HyperGraph.You could also use Altair Compose for signal processing. FFT.pdf
  14. The error message suggests that you reference elements in SURF # 1 (and others) that are not (anymore) in your model. Please update the SURFs.
  15. If it is in a separate file you may have to call it with a INCLUDE statement.
  16. Do you see any waring or info in the converged model files?
  17. .out file → provides a commentary on the solution process Generally we get model data information which is missing.Is is possible to share the .fem file?Will help to debug the issue properly.
  18. It seems you have edited some details from the out file.If confidential please share through secure file dropbox available in my signature.
  19. Please share the .out file of the run?
  20. If you have latest version of HyperWorks 2019, then please check the OptiStruct online help for verification problems. This manual presents solved verification models including NAFEMS problems.
  21. From the above shared image, its pretty clear that you dont have hwsolvers executable which contains Altair Solvers. Request free student edition from below link: https://altairuniversity.com/free-altair-student-edition/
  22. This looks like a license error. Please refer below post.
  23. Faces we check to ensure the connectivity between 3d elements. Please share the screenshot of the region where you want to maintain connectivity.
