Hello,
checking the file before launching the analysis I found surface contact errors:

 

  • WARNING # 4735 No contact element is created for CONTACT 1 at the start of analysis. SRCHDIS if the contact is not for finite / continuous-sliding (TRACK = FINITE / CONSLI) with large displacement analysis.
  • WARNING # 4782 CONTACT interface 1 has 9128 Slave faces that belong to Master surface, indicating likely self-contact condition. Contact us.
  • 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.
  • NOTES # 9199 MSGLMT = STRICT is active, all messages will be printed. MSGLMT = BRIEF or UNREF (in config file or in the input data).

 

Could anyone please provide or check how to rectify the error. 

Thanks in advance.

    It seems you have self contact defined in the model.What is the contact track opted for analysis?FINITE or CONSLI.

    Self contact is supported only for continuous sliding.If it is set to FINITE then change it to CONSLI and run again.

    For Contact Interface 1 set the TRACK option to CONSLI.
