*tie 求助

abaqusww

大家好!

新学abaqus, 最近一个问题实在困扰好久！希望各位大侠指点迷津，万分着急。
我在用tie 来连接cohesive element 和另一部分，为什么老出现这个warning.请问怎么解决tie 的overconstraint 的问题呀？
万分感谢

***WARNING: SOLVER PROBLEM.  ZERO PIVOT WHEN PROCESSING ELEMENT 19 INSTANCE

OVERCONSTRAINT CHECKS:
An overconstraint was detected at one of the Lagrange multipliers associated
with element 19 INSTANCE COHESIVE-1. There are multiple constraints applied directly or chained
constraints that are applied indirectly to this element.
A list of nodes and chained constraints between these nodes that most likely lead to
the detected overconstraint can be printed out to the message file by including
*constraint controls, print=yes.
