切削仿真中,点-面接触与通用接触中设置纯主-从面接触的区别?

如题,我在做3维切削仿真时,刀具与工件的接触使用了面-面接触,其中刀具为刚体、主面,工件选择的节点区域、从面,weighting factor=1。然后运行时有WARNING: A shell surface with shell offsets has either rigid elements or deformable elements made rigid. Rigid surfaces with shell offsets cannot be used with contact pairs with MECHANICAL CONSTRAINT=PENALTY. The shell offsets will not be enforced within the contact domain. Please use general contact instead.
我是不是应该改为使用通用接触,并使用里面的pure master-slave assignments呢?我查了下帮助文档,没发现pure master-slave assignments与surface-surface contact的区别。
希望能得到您们的解答,谢谢!
