Hypermesh/Simlab/Hyperview Crash

edited September 2021 in Community Q&A

I recently got a new Windows PC and installed HyperWorks 2020. After installation, if I tried to open any Hyper product window, the window opens for a second and then the program crashes.

I am still able to use HyperWorks on my old PC (Same OS). I thought it was due to the fact that HW could not create the command.tcl and hmmenu files, so I followed the instructions here and changed the start in folder: https://community.altair.com/community?id=community_question&sys_id=c84688761b2bd0908017dc61ec4bcb68. The issue still persists.

If I go to the new start in folder, I do not see any files created by HW there.

Any help is greatly appreciated.

Thanks,

    Hello Akileshr,

     

    there may be several reasons explaining why the products fails at opening:

    - one or several of the files are corrupted. In AltairOne you can download the software either from the marketplace section, or from the AltairConnect section. In the AltairConnect section, you can have access to the checksum of each executable. This is a code which allows to check the consistency of your package once downloaded. You can use  either PowerShell (https://stackoverflow.com/questions/10521061/how-to-get-an-md5-checksum-in-powershell) or external tools such as Winmd5 to get the cheksum of the package once downloaded. If the code is different, then your package file has been corrupted at import

     

    - special characters in the user name. This is something that has been added by Windows in Microsift 10, but lot of editors are not supporting yet properly this new feature. Please avoid this as much as possible

     

    - graphic board settings. Make sure that you use a valid graphic board for Altair software (ATI or Nvidia professional graphic boards recommended), with the latest version of the driver. Also, if you have a laptop, make sure Altair ssoftware use the graphic board instead of the default graphic chipset

     

    - licensing issue. Make sure youer license is correct. This should nevertheless populate a pop-up if your license is not valid

     

    Best Regards,

    Michael

    It was a Graphic Card issue and one of Altair's support engineers with your GPU team helped me fix it. Essentially, the PC was using the onboard graphic card over the dedicated NVIDIA card.
