最近建模计算一个锯片模型，总是计算不收敛，不知道哪里错了，现上传模型，请高手帮忙分析一下，谢谢了Degree of freedom 4 is not active in this model and can not be restrained
Degree of freedom 5 is not active in this model and can not be restrained
Degree of freedom 6 is not active in this model and can not be restrained
1 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.
There are 151 unconnected regions in the model.
Displacement increment for contact is too big.
提示接触位移增量太大，是不是接触那里没有设置好？还有那些自由度是怎么回事？
论坛不懂怎么上传，不支持格式，所以上传到网盘了，我用的abaqus6.11版：
