报错如下:The *tie pair (assembly_surf-26,assembly_surf-19) is also used as *contact pair. Remove this *contact pair. The same pair of surfaces cannot be specified more than once for *tie and *contact pair. Once a pair of surfaces is used for *tie, it cannot be used again for *contact pair and vice versa.
我感觉我涉及这两个表面的只有tie这一种,不知道哪里有冲突
