  1. Are you looking for Stress-NORM aggregation in topology optimization? You could refer to OptiStruct online help for more detail. We have plenty of tutorial and examples available for optimization.
  2. You could refer to HyperForm (Manufacturing solution Interface)tutorials. HF-5000: Using Result Mapper in HyperCrash In this tutorial, you will learn the procedure for mapping forming results onto structural models using the HyperWorks Results Mapper. HF-6000: Die Structure Optimization
  3. I also tested Radioss + HyperStudy coupling by referring HS-4220 & it works as expected. Please refer below video which covers up to nominal run. HS4220.mp4 boxbeam1.tpl boxbeam1_0000.rad boxbeam1_0001.rad
  4. This seems to happen if function response (DRESP2) is not referenced in either the objective or constraints. If used, error message does not appear.
  5. I suspect this issue is related to naming. Please refer to similar query . If the above solution doesn't works, then please share the required files here.
  6. I was hoping that you could clarify some points.Can you confirm whether I should be able to execute a Hyperstudy analysis with RADIOSS? If it is the case I would be grateful for some tips as I cannot progress beyond a licence error. RADIOSS runs fine from the Hypermesh session.I get RADIOSS to start but it bangs out with a licence error... from task_exe_stdout.txt .. STARTER RUNNING ON 4 THREADS .. CONTROL VARIABLES *** Radflex Error : 200 - Back to checkout*** from JOB.out LICENSE CHECK ERROR -------------------- ERROR : License check failed ! "Radioss" feature not found on license server! Check your License server settings Many thanks Mike
  7. Define PSDM output request for STRESS
  8. Please the check the SimLab load mapping capabilities. Altair for SimLab Learning Center
  9. You could use Model Resource features in HyperSudy for the above requirement.Please refer below online tutorial for same. HS-1080: Set Up an Operator Model
  10. Contact output for linear analysis(Available from OptiStruct version 2019.1) Contact output, such as Contact Force, Traction and Deformation, are available for linear analysis via the CNTF I/O Entry.
  11. Sorry for the late reply.Could you please ensure the starter input deck name should be same during the define model step in HyperStudy.Can you please make sure there is no space or special characters.Above shared files I successfully able to run at my end with HyperStudy Student edition 2019.0. I believe the issue is because of naming.
  12. Time varying convection (Available for Version 2018.0 or higher) 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.
  13. I don't know the use case or application for multiple material in size optimization.Attached is two setup for size optimization with stiffness & thickness parameter. I think if you have objective to do size optimization for five different material then you need to create design variable property relationship five times manually. Note: Multiple-Material Topology Optimization is available from optistruct 2017.1 version. young.fem size1.fem Multiple-Material.zip
  14. As mentioned in the above shared tip and trick,with older version you can do only linear analysis.Switching to latest version would help you to explore many new features of OptiStruct.
  15. Please remove FLAT=1 from the TABLES1 referenced by MGASK.
  16. You could try this axisymmetric analysis with OptiStruct latest version 2019.1.Please refer below tip and trick & for more information refer OptiStruct user guide. https://www.altair.com/resource/optistruct-nonlinear-axisymmetric-analysis
  17. Please make sure to add exact max closure values in loading curve,
  18. 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. You could use Hypermesh interface to define this input.
  19. You have modelling issues in your model.There is no node to node connectivity between design and non design.Use free edges or faces option to clear same.
  20. Please refer to below video where composite analysis and optimization is discussed in detail.
  21. This is resolved in Hotfix Hwdesktop 2019.1.1.Please download it from Altair connect.
  22. This output request is available with latest vesrion of OptiStruct 2019.1
  23. Please refer attached document for FASTFRS from online help. FAST_FR_&_FRS.pdf
  24. CGAP, CGAPG, CWELD, CSEAM, CFAST, RBE1, and CONM are not compatible with LGDISP.
