在模型中插入0厚度的cohensive層后，提交作業，錯誤為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 663 and 7763 on element 4801 of instance PLATE-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.

請大神幫助，感激不盡
