如图，想用abaqus实现在两个处于同一平面的面上分别施加力矩，用两个参考点分别耦合两个面，但是由于存在共用节点会导致过约束的情况，计算会报错：OVERCONSTRAINT CHECKS: NODE 25 INSTANCE PART-1-1 IS USED MORE THAN ONCE AS A COUPLING NODE IN THE *KINEMATIC COUPLING KEYWORD.

1、施加方式必须是将施加扭矩面与参考点coupling吗，coupling面是花键接触面还是花键内圆面呢？2、建立圆柱坐标系，将扭矩施加在参考点哪个轴上呢，R/T/Z? CM1 CM2 CM3?

lsdyna中显示 Error 30434 (INI+434)Sharing nodes is not allowed between slave and master partscoupled using *CONSTRAINED_LAGRANGE_IN_SOLID ctype 2.Node 7 in master part 2怎么解决？
