  2. Hi Arul, Have you tried RFORCE? You can apply a rotational angular velocity and this can be refered in RLAOD1 card.
  3. OK. I am going to discuss this with dev team. I shall get back to you soon.
  4. Today
  5. Hello, It is not necessary to switch the display off while working on purge command. Will you please redirect us to the video where you've seen that...!
  6. Do we have to switch the display off for doing executing the command 'Purge' ? I have seen in some tutorials for doing Volume purge the tutor had offed the display of Surfaces and vice versa for Surface Purge. Is it required to off the display for purge? Thank You
  7. The license is found under the student edition downloads section once the license is approved (takes about 5 days) This order was approved.
  8. We see that your order was delivered, India Students must write to - edu-support@india.altair.com to get the approval of the student edition,
  9. The student edition does not allow command line solving, solvers are interfaced through the app alone.
  10. Please follow the video attached , you can contact local HyperWorks support directly for help setting up server licenses Altair License Manager Installation_12.0.3.wmv
  11. Yes, tried that even on the first try, and both combined
  12. The HyperWorks student edition interfaces with solvers only through HyperMesh (HW Apps) and not through command line or solver manager, Please solve the file through the apps itself,
  13. Michal1509, Can you please confirm if the above has helped you?
  14. Use windows folder options > unhide known extensions, to make sure the file is named altair_lic.dat and not altair_lic.dat.dat, You need to confirm if the Ethernet address in the license file is the correct one and matches the one in your machine. When you open the license file in a text editor you will see an Ethernet address there in a line that says "ETHERNET = The Ethernet ID is the ID of your machine which is exactly 12 hexadecimal numbers. For example D4WRF478F398 Run ipconfig/all in command window and check for physical address under Ethernet adapter local area connection: The listed physical address under Ethernet adapter local area connection should be used to generate the license file, That means if the address provided as above does not match the one in the license file, please request for the license file again with the correct Ethernet ID. You can check your computer’s Ethernet address, by using the almutil -hostid application from the Start > Altair > Tools > Admin tools Menu and compare it with the result in the command window, Alternatively run getmac in command window to find out available Ethernet addresses to cross check as well,
  15. Kindly refer below provided Video for the same -
  16. Hi, I need to carry out frequency response analysis with operating speed. There is no force and I have only speed in rpm as input. How to specify this in Optistruct instead of using SPCD/DAREA card?
  17. Dear Team, I want to create a Mesh without surface on Cylinder End. Both the ends are open for the cylinder. Kindly help me to solve this issue.
  18. Hi @Muge Candogan Please check for rigid modes. Try to constrain the model in all dofs and check if this works.
  19. Hello Rahul, We have performed the suggested steps, i.e. "altair_lic.dat" is uploaded under the security folder and we are still seeing the popup "CADFEKO: Licence error" box when we launch "CADFEKO 2017" application from my desktop machine. The error codes in the popup box are as follows: "ERROR 9161:------" and "Error Code: 9": For further details into the error popup box, please refer to the attachment: Thank you!

  20. Hi, It seems there is some problem in your EIGRL card. Have you entered the range of frequency in it or number of modes. If the range of frequency does not have any mode this issue might come. Please clarify for it.
  21. Hi, Did you try with PARAM>>I64SLV>>YES? If this does not work, please let us know.
  22. 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.
  23. 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
  24. 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.
  25. HI, Virtual Wind Tunnel (VWT) is a vertical solution to perform wind tunnel simulations of vehicles in an efficient manner. You can g through this link http://www.altairuniversity.com/analysis/cfd/virtual-wind-tunnel/ for a short demo on VWT. Also, for webinar on VWT training please visit https://www.youtube.com/watch?v=qm6hvDxjJN8 . Also, please go through this topic which is similar to your query:
  26. Hi all, i have a problem and really need to be helped. I am practicing with HyperMesh and trying to export to fluent. I wonder what if I just export mesh file of an airplane to fluent, and use fluent to build wind tunnel, because build win tunnels with hypermesh is really tough for me. Also, please help/guide me to build Wind tunnels in hypermesh for any airplane, I use the example came with tutorial but no success (follow step by step in tutorial). I would like to know how to build a wind tunnels and complete the export file to fluent. Best regards.
  27. Thank you Andy
