Hi All,

 

I have k file of 370 MB which includes segment pressure for ~0.1 million shell elements. As this is important part, I need small details also. So number of elements in my model is ~3.6 million. I am using 64 bit,16 GB ram, 4 core system. I have done modeling & set up using hypermesh. The model is running with no issues. My problem is when I opening this k file in a new HM (I am using HM2017), the file is not opening. If I delete the Load collector (Segment pres), It is opening properly. 

 

Is this issue related to system requirements/ HM error? Also I have checked with LS PrePost in the same machine, it is opening properly. I am not sure what the issue is?

    Hi Udhay,

    The issue looks this may be due to the large file size and the graphics limitation. Please go through the graphics hardware recommendation in the Help Menu.

    Go to Start>Run> type dxdiag and click on display to see the graphics details of the system.

    Hi Udhay,

    Please disable the onboard graphics and enable the Nvidia card, (you may have to disable it through bios, please contact your manufacturer support for how to disable / switch the cards). Switching to an older driver or upgrade to the latest version. Please mind, to uninstall the old one completely.

    Hi Udhay,

    It seems like this is due to system limitations. Can you share the model so that I will try opening the same in my system.

    You can share the model through secure dropbox, which will be safe and secure.

    Hi George,

     

    I have dropped files in drop box. As the original model is under confidentiality agreement, I have uploaded the similar model which gives same issue. please try it in your end and let me know your comments.

    Hi Rohith,

    As mentioned above i able to import .k file without pressure. I see you have only plate with tetrahedral element & enclose shell elements where you applied pressure.

    I would recommend you to create pressure with faces option(just pick one face of tet element).No need to have 2d element faces & then export/import .k file.

    Hi Rahul,

     

    Thanks for your reply.

     

    My model requires 2d elements with 0.1mm thick.

     

    But I have tried with deleted 2d elements also. That is also not opening.

    I see in your model( .k file without pressure) only one component.Organize 2d elements in to new component.For 2d elements normal are not aligned properly.Correct it by adjust normal option or use 3d element faces.I believe by correcting element normal it should work.
