如題，我在做3維切削仿真時，刀具與工件的接觸使用了面-面接觸，其中刀具為剛體、主面，工件選擇的節(jié)點區(qū)域、從面，weighting factor=1。然后運行時有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.

我是不是應(yīng)該改為使用通用接觸，并使用里面的pure master-slave assignments呢？我查了下幫助文檔，沒發(fā)現(xiàn)pure master-slave assignments與surface-surface contact的區(qū)別。

希望能得到您們的解答，謝謝！
