Model (geometry and elements) disappeared suddenly

Altair Forum User

Hello,

I was working on my FEA creating bars to join the RBE2 I'm using to simulate bolts. Suddenly, my model has disappeared from the graphics area. In the corner which is below in the right side, the scale line seems to show a bug. All the information about the components is still in the model tab, but i can't find a way to visualize the model again.

I've tried fitting the model, checked no transparency is selected, components are activated...

Anyone has any idea about what could be happening? I have no problems with sharing the model if necessary.

Thanks for your attention,

Julio

Hi,

right-click the Assembly Hierarchy>Show, then ctrl+middle mouse button to fit the model to screen.

Share the model if the issue persists-file size is a good indicator if elements/geometry are in the model.

I've tried your instructions but it doesn't work. I've also checked the file size and it is 15mb, so i guess the geometry and elements are still in there.

I've tried to upload the model to this page but i think it is too big for this site, so, if it doesn't appear attached, could you give me an email address to send it to you?

I really appreciate your help.

Hi Julio,

May be when you're doing some operation the script could have disabled graphics, but since the operation failed it didn't enable it again.

You can go to Preferences->Script Performance and uncheck all options and press apply.

Otherwise it could be some graphics card/driver issues too. Try doing the same operation in another machine, if it is not reproducible, check if graphics card is compatible with Hyperworks, update driver, and delete Hyperworks temp files.

Hi again,

I've followed your instructions but everything seems to be ok. About the graphics card/driver issues, it's possible but I've already been working on the model for a long time, so why would I get problems with the graphics now? I'm sorry that I couldn't find another machine with HyperWorks installed to check reproducibilty.

When I got the error, I saved the model because I had made big progress that day. I'm attaching the model just in case any of you could help me to get it back.

I want to say thanks again for the help, I really appreciate it.

Hi Julio,

There seem to be some issue with Student Edition, I was able to recover the model by exporting as .rad and re-importing again but there is a possible loss of data.

If you can share the model before the issue and a video showing when it losing the data, it can be fixed in future software release.

Thanks.

@Julio Do you have any backup of your working model?

Altair Forum User

Q.Nguyen-Dai, I saved the model some days ago, so i'll continue working with it. It is not as advanced as the one i was working with, but it could had been worse.

Livil Lyle, when I develop the model until i reach the same point where i was, i can share if the same problem shows up.

Hi everyone,

I've been working in a model for a few months, suddenly, and after meshing (solid map -> multisolids) everything disappeared and the scale bar is 'empty', just as Julio's case.

The model and geometry is still there as the file size is 541mb (very big model) and when I try to shown/hide components and assembly it takes its time. I followed the recommendations posted in here but with no luck.

From what can i see, Julio just went back to a previous version...Is there anything else I can do before going back to a back-up copy?

Thank you for your time and help,
