Dear Venkata,

I don't think that works. If you check in Ansys classic you should see a
component "nodes" that has your nodes included. But there is no components
called "node", "no1", "nodeno2" etc, which you need.

If you don't care which node is the primary node I think you can use

cp,next, ux, all

instead. If you need to set one certain node as primary node one way could
be to have that node in a Named selection by itself. Use CMSEL to select
the node and *GET,asfg,sadg,sdag (don't remember the exact formulation) to
dump the node number into a parameter (primary_node). Have the rest of the
nodes in another Named selection and use *GET to get the lowest node number
and the number of nodes in the component. Do a loop over the number of
nodes in the 2nd set and use CP to create a coupling between "primary_node"
and each node in the 2nd set.

>From the back of my head...

CMSEL,S,named_selection_1_containing_the_first_node
*GET,node1,NODE,0,NUM,MIN

CMSEL,S,named_selection_2
*GET,min_nu_no,NODE,0,num,min
*GET,nu_no,NODE,0,COUNT,

mn=min_nu_no
*DO,i,1,nu_no
CP,NEXT,UX,node1,mn,
mn=NDNEXT(0)
*ENDDO

Dear Peter,
I worked with named selection also. I created named selection as nodes
(Component name) of nodes and used following script
/prep7
alls
Cmsel,r,nodes
Cp,next,ux,node no1,nodeno2
/replot

I hope this is the sequence we need to follow for ansys classic.

Did you define node1 and node2? The way to do it is to use Named
Selections, and in your case defining one vertex as node1 and the other
vertex as node2.

Dear members,



I am working on creating a coupling joint in Ansys Workbench
environment.



I tried by just creating coupling between two beams in x-direction by
Ansys classic command



Cp, next, Ux, node1, node2



I could not find it appear even in FE modeler or Ansys Classic after
exporting the same model.



I tried in a reverse way also I;e Creating a coupling in ansys classic
and export to FE modeler and then Design modeler.



Neither way it worked. Please throw some light on creating couplings in
workbench. We simulate various kinematic joints through coupling
equations.





Regards

Venkata Krishna
