  2. license error 9 in some analysis

    You need to place the license file in the security folder within the FEKO folder,
  3. Question about .mat file generated by FEKO

    From email to support I am using a student version of FEKO, and I have a problem while trying to export the impedance matrix from FEKO into MATLAB. I get an error saying that the .mat file might be corrupted . I would be very grateful if you could help me in this issue.
  4. Could my license be expired? (Error 6 and Error 9)

    The license should be placed in the security folder itself and not the bin folder, see

  6. Hi there, i am using HyperStudy with optistruct solver to do an optimization. Is there a possibility to change the number of cpu´s used by the solver? thanks Thomas
  7. Problem with HyperMesh in student edition

    Have you switched to a supported card? also the driver version may need to be updated on the card...
  8. Altair licensing service failed to start

    Can you make sure the license is generated for the correct ethernet ID,
  9. convert a STL mesh file into solid part

    Do you know how to convert a STL mesh file into solid part for finite element analysis? Using stereo-photogrametry tech I have a geometry of the structure in the STL format. Now I try to import it into hypermesh for FEM analysis. I will appreciate it if you help me.
  10. HyperMesh Segmentation Error

    You must also hmsettings.tcl, hmmenu.set and command.cmf. also hwsettings.xml in my documents (if that is the working directory), restart the app and try.

  13. Problem with cylindrical roller bearings

    Hello everyone, I am creating a numerical model of a cylindrical roller bearings using Hypermesh. I started with one cylindrical roller with diameter 5mm. The contact area I mesh with 2D-automesh, to get the mesh finer at the contact. Afterwards I use "tetra mesh"-panel to create a mesh to all solids. I have refine the contact to 0.025mm, but I do not get the analytically results of Hertzian pressure (more than 30% deviation). The analysis is non-linear-quasi-static, the contact SLIDE, NLPARAM NINC=5 and the loadstep is set to NLSTAT. If someone could give me tips for mesh of cylindrical rollers, I would be infinitely grateful. And sometimes comes the ERROR # 941 NON-CONVERGENT NONLINEAR ITERATIONS FOR SUBCASE 1. What can I do to check what I need to change in my model? Regards, Martin
  14. Average Stress

    We installed some strain gauges on a suspension part of a trailer which I need to simulate in Hyperworks. These strain gauges have a typical size of 6x6mm. I want to represent these strain gauges in my FE-model and compare analysis results with the measurements. First of all I defined my surface that represents the strain gauge by Geometry > Create > etc. . After that I used 2D-Automesh to create a fine mesh and created a tetra mesh on all geometry with the option "match existing mesh". Now to my problem: I need the average strain of all nodes on my "strain gauge-surface". I want to use this information to compare this average strain with the measurement results. I have seven node sets which i have to evaluate, so a manual procedure is to time-consuming. Do you know a tool or an script that is able to do that?
  15. Hyperwork 14 student edition problem

    could you tell us the operating system in use and also if you tested if the software is downloaded correctly using checksum
  16. licencse error 6

    As long as the file is named correctly and placed in the security folder it should work correctly, you do not need the environment variable, however if you are going to use the variable the value of the variable should be the entire path of the fil not just altair_lic.dat as it is here also this must be a system variable
  17. license error

    The same account is fine.
  18. Connection of Shells to Solid

    Hello, I have a model in which a shell plate is connected to Solids. To account for the rotational degrees of freedom of the solid elements, additional membrane elements wer created, which should prevent the solids from rotating. There are several issues related to this model. 1) Can you please describe a proper way to define the membrane shell elements on top of the solids? 2) The deformation in the analysis is too large (meaning the solid structure is rotating). Can you please advice how to properly define the connection between shells and solids to prevent the rotation?
  19. license error

    Hi, 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,

  21. License error 9

    You have to request for a new license with the correct ethernet ID of your computer, the license file must not be edited.
  22. No Ethernet Port

    Hi Robert, You need to request again here http://studentedition.altair.com/ you can use the Wireless LAN adapter Wi-Fi address.

  24. License Error while Radioss Run

    Are you using the HyperWorks Student Edition or the full version? please check if you have sufficient count of licenses if you are using a server license and also if the RADIOSS feature is available in the license file,
