Hello YADE users,

I try to control stress path in True triaxial test follow the paper:
[1] http://cemmlab.webhost.uic.edu/15-2-1992.pdf

In [1] the author controls stress path by varying the value of b =(sigma2-sigma3)/(sigma1-sigma3) and keep the mean stress sigmaMean = (sigma1+sigma2+sigma3)/3 constant during the test.

I followed this approach and modified the script [2]: https://github.com/yade/trunk/blob/master/examples/triax-tutorial/script-session1.py
In which i applied strain-controlled for direction1, and stress control for direction 2 and 3. The applied stress sigma2 and sigma2 are calculated from sigma1, b and sigmaMean. I used PyRunner to update the applied stress for every iteration.
However, the result showed that  sigma2 and sigma3 always kept constant.

Could any YADE experts show me what's wrong about my approach?

Thank you in advance!
Mike
