Hello everyone.

I am working with nonlinear spring (Combin39) on Workbench. To do this, I added longitudinal spring and added command as follow:

ET,_sid,COMBIN39

KEYOPT,_sid,1,0

KEYOPT,_sid,2,0

KEYOPT,_sid,3,1

KEYOPT,_sid,4,0

KEYOPT,_sid,6,1

R,_sid,0,0,0.1,4000,1,6000

RMORE,3,8000,9.2,10600,12,3500

The spring working well (by seeing the force-displacement responses). My problem is: I want to get the result of spring (force carry by spring). How can I get that? 
(I add Probe -> Spring into solution, but the result show 0 value, and when I suppressed the command, I can get the value of spring in Probe).

Thank you in advance.

 Try the APDL code that was required for the COMBIN40 spring element.

Dear Peteroznewman.

Thank you for your reply.

However, I am quite new with Command in Workbench. So I am still not get your point. Do you mean using Code for Combin40 to apply for Combine39? 

Please help me out of this problem.

Thank you once again.

Dear Vodanh,

I mean adding a Command object in the solution branch, like I had to for a COMBIN40 spring to see its force output.

Note that some of the text in the above command object is related to the command that created the COMBIN40 element by command under the spring as shown below. You would change the first block to make it a COMBIN39, but the second block sets up names that are used above.
