Failure due to negative volume.
I am doing an impact analysis of bullet on a ceramic plate. The error I get is 'Elements eroded due to negative volume' , 'failure due to negative volume'. I have attached .k file below. All the dimensions are in [g cm us Mbar]
sorry. k file is not allowed here.
Sorry I’ll address the issue with uploading .k files. For now just make a copy of the file and rename it to a .txt file and upload it.
Are you modeling erosion in you simulation?
Hello. Thanks for replying. I have attached the .txt file here. The contact type between the bullet and the targets is CONTACT_ERODING_SURFACE_TO_SURFACE .
EDIT- I cannot attach .txt file too. Don't know whats the problem with sharing.
Sorry, it should be addressed. There are spam controls that prevent attachments occasionally, it should work now.
I'm sincerely sorry that I never got back to you on this. Things got very busy for me. Did you get this issue solved? It looked like it could have been an issue with you *contact_eroding_surface_to_surface. Maybe try a segment set instead of node set for that contact?
