A facet that is part of a general contact surface has coincident nodes. A facet with coincident nodes cannot be part of a general contact surface. See nodes 244 and 243 on element 552 of instance PART-4-1. Please check the nodal coordinates of nodes of this element. Also, please check if these nodes are slave nodes in a *TIE definition. Adjusting the slave node coordinates of improperly defined *TIE definitions may cause excessive distortions of the underlying elements resulting in collapsed facets. If the nodes are slave nodes in a *TIE definition, please check the *TIE definition for consistency, making sure that there are no common nodes between the slave and master surfaces.  
   这是错误提示！就是环扣板定义接触的那个地方！但是我总感觉定义的没有什么错误！如果哪位高手想要模型看看的话，加我的QQ：379102712谢谢！     非常的感谢！我弄了好长时间没有弄好，就是把环口板的一个边线和主管上的线tie到一块了！就是这里出现的错误！

直接一体划网格好了，不需要作连接或者接触。

同意ls， 二者merge为一个part就行了。

merge成为一个part是mesh merge还是geometry merge比较好？
