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.

   当我要求结构某点的位移-荷载曲线的时候，在施力点建立了一个参考点，并于coupling将其与结构相应的面上进行绑定，再对该参考点进行加载。但再计算过程中，warnning里面却出现了

   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.

   走过路过的大神们，指点一下，万分感谢。
