I have implemented them in both a 2D axysimmetric model and a 3D model.
You have to use the *EQUATION and relate displacement of equivalent
nodes (N1 and N2) in opposite faces to the motion of a "master" node M,
like this
u(N2)-U(N1)=u(M)-U(origin)
As origin node is encastred u(origin)=0, so it is only a three term eq.
you can write it like
1*u(N2)+(-1)*u(N1)+(-1)*u(M)=0
that is the way you have to implement it in ABAQUS. Do that for all N2
and N1 pairs in each face
Take care with repeating nodes N2 in two different equations, because
they are slaves, and cannot be used twice.
