Problem with Surface Tie...

[loki3000]

Hello. i get this error when trying to set up a tie between the individual parts (surfaces):
***WARNING: OVERCONSTRAINT CHECKS: NODE 192469 IS USED MORE THAN ONCE AS A
SLAVE NODE IN THE *TIE KEYWORD. THE CONSTRAINT BETWEEN THIS NODE
AND THE MASTER SURFACE WITH NODE 500058 IS REMOVED.

***ERROR: OVERCONSTRAINT CHECKS: NODE 192469 IS USED MORE THAN ONCE AS A SLAVE
NODE IN THE *TIE KEYWORD. REMOVE MULTIPLE USAGE OF THIS NODE AS A
SLAVE NODE OR COMBINE THE MASTER SURFACES TOGETHER AND USE THIS
SURFACE INSTEAD.
***NOTE: DUE TO AN INPUT ERROR THE ANALYSIS PRE-PROCESSOR HAS BEEN UNABLE TO
INTERPRET SOME DATA. SUBSEQUENT ERRORS MAY BE CAUSED BY THIS OMISSION


is there any way to mitigate this problem in the INP file, as i am editing the model that way.
I think the error is due to a node beign a part of 2 slave surfaces at once (?), as i have a highly complex geometry. can i just delete it from the surface nodeset (i doubt it though)?

does anyone know any other way to fix the problem?
the *TIE command is surface to surface, abaqus cae (standard).

Try switing your master and slave surfaces around.

same problem, only different nodes...
I will try node to surface now, if it'll be any better.

anything else?

 

[loki3000]

still nothing
i've tried node to surface, s-to-s, reversed the order for master-slave and also
*constraint controls, no checks
*constraint controls, delete slave

to no success.

go into the node set of one of the definitions and delete the offending node
