Hi Robert,


Thanks for your time and recommendation.


Hi Hien,

thanks for recommendation. I meant force network.



Cheers,

Hien N.G. NGUYEN proposed the following answer:
Do you mean the force network instead? (force network: serie of lines
presenting all interactions, and lines' thickness represent force's
magnitude?) Be careful to use the terminology 'force-chain'.

If so, you can do it outside of YADE, try saving interactions info data and 
plot it with matplotlib or mayavi.
Or you can do it the simple way: save YADE model (yade.gz for example) and you 
can access this every via YADE UI.
Load the saved model, then in the UI window, do this:
Display Tab -> OpenGLRenderer -> tick 'intrPhys'
You can also hide spheres by unticking 'shape'

Good luck
Hien

Also, if you search this forum for "force chain" you will find several
other answered questions describing how to visualize force chains.

Seti is still having a problem:
Hi Robert,

thanks for reply and sorry for not being specific.

I meant tracking the force chains in cohesive triaxial tests - Visual
observation in 3d Sample


Thanks,
Seti

Robert Caulk proposed the following answer:
Hello,

Are you asking us about how to record the strain of a specimen being
triaxially compressed by TriaxialStressController() [1]?

If your TriaxialStressController is labeled "triax":

e11, e22, e33 = triax.strain[0], triax.strain[1], triax.strain[2]

If you are more interested in the physical dimensions of the sample,
rather than the strain:

width, depth, height = triax.width, triax.depth, triax.height

-Robert
