分析时警告：Two faces on opposite surfaces in a contact are connected at a node

LKS042

分析的时候出现这样的警告：
** Warning: Two faces (DBIDs: 8601788 & 8537338) on opposite
            surfaces in a contact (DBID: 8362146) are
            connected at a node (DBID: 8363110). This prevents
            the surfaces from moving completely apart during
            a contact analysis. If this is not what you
            intended, please edit your model appropriately.
请问这是什么意思啊，是接触有问题吗？怎么解决啊？
