Warning message - Contact Simulation 4690 (CONSTFF) and (UPCLSTFF)

Hey everyone,

 

in my SOL 401 nonlinear statics analysis f06-file I get a warning message concerning the contact/glue condition.  I have 4 contacts - 3 surface-to-surface contacts and 1 glue contact.

 

USER WARNING MESSAGE 4690 (CONSTFF)
     ONE OR MORE HITTING AND TARGET ELEMENT FACES INCLUDED IN GLUE/CONTACT DEFINITION SHARE COMMON NODES. 
     GLUE/CONTACT STIFFNESS COMPUTED MAY BE DIFFERENT THAN WHEN THE HITTING AND TARGET FACES DO NOT SHARE
     ANY COMMON NODES.
 *** USER WARNING MESSAGE 4690 (UPGLSTFF)
     ONE OR MORE HITTING AND TARGET ELEMENT FACES INCLUDED IN GLUE/CONTACT DEFINITION SHARE COMMON NODES. 
     GLUE/CONTACT STIFFNESS COMPUTED MAY BE DIFFERENT THAN WHEN THE HITTING AND TARGET FACES DO NOT SHARE

 

If I check the solution the contact performs in a reasonable manner. I wasn't able to narrow down what causes the warning message though. Any ideas?

 

Regards
