Question #659526 on Yade changed:
https://answers.launchpad.net/yade/+question/659526

Jan Stránský proposed the following answer:
There is zero stress because there are no interactions in your model. You can try
aabbExtrema()
and compare it to 
O.bodies[triax.wall_right_id].state.pos
There is simply a gap between the wall and spheres.

Anyway, you created spheres by makeCloud, which makes a loose packing,
so you would get very low stress anyway. Consider to use some
"precompaction" either using randomDensePack or the
TriaxialStressController itself.

Concerning the error, have you uncommented "if 1:" the line above?

> File "newtriaxtest.py", line 184

if you are referring to the original script, it is better to use that
one also for testing, e.g. here the error message, line 184 point to
nowhere in the original script..

cheers
Jan
