我將網(wǎng)格從hypermesh導(dǎo)入abaqus，進行耦合，結(jié)果分析時這樣

1 nodes are used more than once as a slave node in *TIE keyword. These constraints are not removed either due to the presence of *CONSTRAINT CONTROLS,NO CHANGES keyword or because removing the constraints might affect the model. The nodes have been identified in node set ErrNodeOverconTieSlave.

我查看了我建的約束，只有一個，邊界條件也并不在這個點上，

*Node

  *Nset, nset=ASSEMBLY_M_SET-2

  *Nset, nset=ASSEMBLY_SET-1

  *Nset, nset=ASSEMBLY_SET-4

  *Nset, nset=ASSEMBLY_S_SET-2

  *surface, type=NODE, name=ASSEMBLY_S_SET-2_CNS_

  *surface, type=NODE, name=ASSEMBLY_S_SET-2_CNS_

  *coupling, constraintname=ASSEMBLY_CONSTRAINT-1, refnode=ASSEMBLY_M_SET-2, surface=ASSEMBLY_S_SET-2_CNS_

  *coupling, constraintname=ASSEMBLY_CONSTRAINT-1, refnode=ASSEMBLY_M_SET-2, surface=ASSEMBLY_S_SET-2_CNS_

  *coupling, constraintname=ASSEMBLY_CONSTRAINT-1, refnode=ASSEMBLY_M_SET-2, surface=ASSEMBLY_S_SET-2_CNS_

請問各位大神，怎么回事呀，要怎么改呀
