Dear all . I have the problem with create rotation of Crank in ABAQUS. I have the only mesh models include 3 part in ABAQUS. I want o create the rotation crank and link this rotation to 2 part other. I try to use Coupling Kinematic and make the rotation of all node crank into RP with only constrain UR3. And after that I use BC for RP with UR3 rotation, but it not working. The coupling only working with constrain ( All DOF in coupling kinematic constrains) and use BC also. But If I do that, All node of Crank like with Rigid body ( because all DOF of node will constraints into RP) , the rotation will work howerver, when I apply load, no exist stress in crank. Because this crank if deformation part. I wanna use MPC constrains, but I don't know which type of MPC is suitable ( may be PIN type ) but I how to choose node to constraint into RP ( all node or just surface of crank) and BC for that. Is there any one know how can I  solve that and can some one propose any way for this problem. Thank every one.

P/s. The crank model include 3 part in 1 PART of ABAQUS (instance), it'n geometry model. THis fiel I upload here I found to show Kinematic coupling in ABAQUS. But in v6.13 I have the option choose all node of Crank for Salve node and choose surface. But I see in abaqus , it only mention for Surface.Why ?? And If Use kinematic constraints ( active all DOF), the crank like with Rifgid body, Right ??
