Hello Philippe,

Have you tried the following in LS-PrePost?

  • Update your graphics card drivers?
  • Use the normal renderer in LS-PrePost by pressing CTRL + L:

  • Output the LS-PrePost_info.txt file by pressing CTRL + O in LS-PrePost. This file contains information about your graphics hardware, drivers and LS-PrePost settings. Note that Ansys employees cannot download files on the Ansys Forum (for legal reasons), but you can post the content of the LS-PrePost_info.txt file in a post if you want. This will help us and developers to troubleshoot the problem.

Also, note that I never save project file .proj when working with LS-PrePost; I only save the .k file and I don't see crashes often. I see crashes sometimes with very large models, but not with models with less than 50k elements.

If you are a commercial customer, you can create a support case on the Ansys Customer Support Space (ACSS):

customer.ansys.com

This way, we will be able to exchange files and better help you.

 

Let me know if this helps.

 

Reno.
