Venkat,

What error are you getting in Workbench (look at the 'Solution Information' to view the Solver Output)? If it solves in Classic, but not in WB, odds are you're missing some APDL to properly setup the solve.

I see that you put in a /solu, which would be my first guess at why it's not solving. Looking at your last few lines of the snippet...you select a nodal component and apply a force to it. Do you have an 'allsel,all' included as well? If the snippet were left as is, you would get a bunch of warning saying that "node x is unselected" or something like that.

Long story short, make sure that any command snippet you insert in the Environment level of Simulation ends with:

/solu
allsel,all

This is just a guess, the Solver Output should tell you what's going on (look near the end). I'm a little confused as to what you mean by "How to see force symbols in this problem". If you're trying to view the APDL applied BCs in Simulation, you're out of luck. If you're trying to view them in Classic, then you should be able to view them by using the /pbc command.


Hope this helps,

Hi edo, Peter,
Thanks for your inputs. I could able to generate Coupling equations similar to ansys classic in Ansys Workbench environment.Infact I tried everything in Workbench itself.

/prep7
cmsel,,node1 !!!First nodal component
cmsel,a,node2 !!!Second Nodal component
cp,1,ux,all
/solu
fini

/prep7
cmsel,,node3
cmsel,a,node4
cp,2,ux,all
/solu
fini

/prep7
cmsel,,node5 !!At the end of second shell top corner
f,all,fx,100
/solu
fini

/prep7
cmsel,,node6 !!!Bottom corner
f,all,fx,100
/solu
-->I tried above script in a single command and I could see coupling equations generated between two shells of 10mm thickness side by side ( top and bottom end nodes). Node5 and node6 for applying force.

--> I tried applying forces as a nodal component because other wise I could not see them if I plot boundary conditions. Even if I try this nodal components I am finding a new element cload,. How to see force symbols in this problem?

-->I checked the model in ansys classic and that is the way I want to see the couplings, However I could not solve the problem in WB and in classic it was solved.

Hi,
which section of the SIMULATION TOOL are you defining the CP equation in?
did you try to define these nodes in DESIGN MODELER as POINT...and then in SIMULATION applying the CP equation?
regards
edo

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
