Crash when opening a large file

Coreform Cubit
#1

I have a quite huge geometry (624MB .sat file). I can import it and save it as a .cub5 file, but failed to open it again. The .cub5 file takes 690MB storage. It has arround 3000 simple volumes.

Is cubit capable of processing such big file? Where can I check the log file.

#2

Yes Cubit is normally capable of handling this file size.

Could you maybe share your geometry. I will try to reproduce this.

Which Cubit Version are you using?

Thank you so much. I’ve uploaded it as https://transfer.coreform.com/76uTpd5h5u/step5_final.sat.
I’m using Cubit 2024.8.

Sorry to bother u again. Do you get error when reopening the saved file @Norbert_Hofbauer ?

Hello @WayneYY,
yes i can reproduce this. I will need some time to find the cause of this.

When I open large cubit files (around 500~100 MB), thre progress panel always shows “Saving CBT***.tmp files”, which cost a lot of time. It really start loading the large files (Progress Building **** CUBIT Entities xx% ) after this progress. Those “CBT***.tmp” files locate in my C:/ disk. Can I avoid saving for opening these temporary files or are they mandatory?

Hi @WayneYY,
you could try to turn undo off. Usually those files are related to the undo functionality.

It works great, thank you :slight_smile:
