Coupling nodes about a cylinder

Hi all,

Below you'll find an image of a hollow tube which decreases in radius. I have 120 evenly distributed points along its spline and I want displace each point by a known (x,y,z) amount. To my mind I would need to create 120 remote points and couple its surrounding nodes. To couple the nodes I need to incorporate a feature similar to that of the pinball in WB which is creating a cylinder with a known radius and a  length of 0.5mm (Legth between spline points is 1mm).

In doing so I have created a remote point, scoped it to the the geometry and inserted an adpl command. Below is my code for the first remote point. 

type,tid

mat ,cid

real,cid

sectype,1,contact,cylinder,tube101,0 

secdata,-21.85699,25.22953,-12.28117,-21.27785326,25.22953,-13.08039048

et,cid,174

et,tid,170

keyopt,cid,2,2

keyopt,cid,4,3

keyopt,cid,12,5

keyopt,tid,2,1

keyopt,tid,4,111111

So far I have set the parameters for the target and contact elements, but i am having a hard time establishing the region needed to couple the nodes. I have used the sectype and secdata command to determine the shape needed to encapsulate the nodes. I tried running the code but all I obtain is a displacement about the whole object when I want it constrained specifically by the region encapsulated by the cylinder.

Any help will be greatly appreciated,

Nero
