Kinematic Coupling

[mereaux]

Hello everybody,

Could someone explain to me, what is the kinematic coupling in abaqus. I have read the user manual. But I do not understand what is the function of the reference point?
Should this reference point have boundaries conditions? What happen then to the coupling nodes?

thank you!

Hello Mereaux,
the kinematic Coupling is used to handle loadcases easier. For example: all the nodes at a surface connected to a reference node which has a displacement in the 1 direction must do the same if the degree of freedom is coupled to the reference node. there is no relative motion between the node and the surface in the 1 direction.
