Contactsurfs and interfaces

Hello,

I need help with my project of Master Thesis. I would like to make an optimization of drill body. I created volume tetra mesh in three components and defined contact surfs and interfaces between two components (which I presented in photo). The problem is I receive errors:

" *** ERROR 14: Missing element # 8172 referenced by SURF # 2.
*** ERROR 14: Missing element # 8173 referenced by SURF # 2.
*** Errors with missing, incorrect or duplicate IDs found 1006 times."

When I defined contact surfs and interfaces for simple cubic solids I receive good results, what suggest that I have created correct contact surfs.

Maybe with complex parts like that there are different steps to create contactsurfs or I should create different mesh?

Thanks very much for your help,

Kacper

    Have you deleted any elements later after defining contact surfs.

    Also have you used AutoContacts ?You wont have to spend time creating contacts and groups, it will do the things for you. You can review to verify.

     

    To do that:

    Go to tools-Contact browser-right click in browser and select auto contacts.

    Thank you for your response.

    I created AutoContacts and receive next error, which I included in the photos. Could you help with that message?
