  1. Hi Arul, Have you tried RFORCE? You can apply a rotational angular velocity and this can be refered in RLAOD1 card.
  2. OK. I am going to discuss this with dev team. I shall get back to you soon.
  3. Hi @Muge Candogan Please check for rigid modes. Try to constrain the model in all dofs and check if this works.
  4. Hi, Did you try with PARAM>>I64SLV>>YES? If this does not work, please let us know.
  5. hi @Rajendra Prasad Error 5408 indicated that the solver cannot find any mode between the bounds you specified in the EIGRL card, thus it cannot proceed with the frequency response solution. Please increase the upper bound to a higher value. You may want to run just a normal mode solution (ND=10) and see what is the lowest frequency and then adjust the upper bound accordingly for the frequency response analysis subcase.
  6. Hi @wu.chia.yu PCOMPG modelling is zone based where as using PCOMPP it is ply based. Here is a tutorial which shows how to model using PCOMPG. OS-1060_ Analysis of a Composite Aircraft Structure using PCOMPG.pdf
  7. Hi @franky To define fluid component for a coupled fluid structural analysis, select all elements of fluid component(s)>>CARD EDIT>>activate CD-1 as shown in image.
  8. Hi DInesh, Can you share the model file using file transfer link in my signature below?
  9. @jahnavi No problem unless you see any error messages.
  10. @Merula Maybe I should have said as initial material fraction instead of VF. So from help, For runs with constrained mass, the default is reset to the constraint value. If mass is not the objective function and is not constrained, the default is 0.6. According to help, you are correct, but before I confirm, let me investigate on the same.
  11. Hi @ahenkes1 You could try using the 64bit integer version of OS, which does not have any size limitations. Go to PARAM>>I64SLV>>YES
  12. Hi @Luís Felipe What is the OS you are using and version of HyperWorks? Can you re-check the command used, maybe it is pointing to a wrong folder?
  13. Hi @samson05 Unfortunately it is not possible to see rigid bodies when you use .odb. Dev team is working on it to introduce this in coming version. As a workaround, load .inp as model file and .odb as result file and check if you are able to see rigids.
  14. Hi Rupali, Can you share the model file?
  15. Hi @riham1994 Can you run the same on MotionSolve 13.0 or 14.0 and check if that helps?
