abaqus-XFEM裂纹模拟出现的问题

我是按照一个例子一步步做下来，没得到它的结果，不知道怎么调整，求各位帮助！出现的error如下：
The maximum normal separation at failure must be greater than zero
The maximum shear separation at failure must be greater than zero for cohesive elements or surface_based cohesive behavior; otherwise, it will be assigned the same value of the maximum normal separation.
The *damage evolution option has to be specified if the *damage initiation is used
The maximum normal traction at failure must be greater than zero
The *damage evolution option has to be specified if the *damage initiation is used
