Tie two object with reference point

[farzadkarami]

hello

I simulated a flat rolling process with two 2D Deformable shell parts, then using a tie constraint ,tied an analytical rigid wire part to the roller for assigning rotation velocity and other condition using a Reference point on Analytical rigid part, but this Error comes up :

"
Unable to locate node set assembly_workpeice-1_workpeice-1-refpt_. The node set must have been previously defined.
Node set assembly_roller-1_roller-1-refpt_ has not been defined
Node set assembly_roller-1_roller-1-refpt_ has not been defined
Unable to locate node set assembly_roller-1_roller-1-refpt_. The node set must have been previously defined.
"
.
.
the question is does this type of tie constraint is correct? and why Abaqus keep saying that?!!

I don't understand the situation. Post an image and describe it for people who don't know your model.

here it is. i attached the assembly model.
i want to define a rotational and transational velocity to the roller(circle) that is going to pass over the workpiece(rectangle).
how can i model this process ?!
