Hi,

I try to make a contact manually, with contact surfaces and interface. The components are two surfaces with laminate. I made another ones and run the simulation successfully.

However this time I have problems to run it. A warning message appear in the output file:

*** INFORMATION # 4739

 The structure of surface-to-surface contact element is quite different than that of node-to-surface contact element. No internal CGAP/CGAPG elements are created for surface-to-surface contact.

 

 *** WARNING # 4735

 CONTACT interface 1 has no contact element created.

 Make sure that there are Slave and Master objects within SRCHDIS distance.

 

Could you help me with this problem?

Thank you

    Hi,

     

    From the warning message what I understood is that there are no compatible elements. What type of contact are you using?

    Have you created any contact surfaces for interface?

    Hi,

     

    Firstly I make two contactsurfs (with elements) between the surfaces. As show below:

    When I have both contact surface I create the interface
