Whenever a translation (rotation) dof at a node is constrained by a kinematic coupling definition the translation (rotation) dofs for that node cannot be included in any other constraint including mpcs, rigid bodies, etc.

   當我要求結構某點的位移-荷載曲線的時候，在施力點建立了一個參考點，并于coupling將其與結構相應的面上進行綁定，再對該參考點進行加載。但再計算過程中，warnning里面卻出現了

   Whenever a translation (rotation) dof at a node is constrained by a kinematic coupling definition the translation (rotation) dofs for that node cannot be included in any other constraint including mpcs, rigid bodies, etc.

   走過路過的大神們，指點一下，萬分感謝。
