Contact pairs in ANSYS

Contact pairs in ANSYS

Contact pairs in ANSYS

(OP)
Hi ,I am doing a finite element analyses using ANSYS Workbench 15.0.
The model contain contact elements type bonded, the later were combined with CZM. When I solve the model the following warning appears:

WARNING: ' ANSYS has found the contact pairs have similar mesh patterns which can cause over-constraint. ANSYS will deactivate the current pair and keep its companion pair.

I am facing a convergence problem due to contacts and I am thinking that this may be the solution of the convergence problem. I would like to know the meaning of this warning. waiting for your response, Thanks.

Hopefully this thread will help: link.


Kind regards,

Thank you Jason for your replying, It's helped me to understand many things, but I still didn't understand it rightly

Yes, I using contact type bonded + for each contact pairs I added a CZM values

RE: Contact pairs in ANSYS

It seems that you are applying multiple contact pairs, you can suppress the contact pair objects one by one and figure out which pairs cause that warning. I don't know what does your CZM stand for, you may temporarily remove the CZM values and see if the warning goes away.
