Question #707148 on Yade changed:
https://answers.launchpad.net/yade/+question/707148

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

1) Yes
2) triax.py
3) How do I achieve servo control?
4) [1]
    - what does "are destroyed" mean?
    - please provide a MWE
5) triax.py

Of course, triax.py is just a primitive approach - a cylindrical surface divided in triangles with fixed force.
It will not work if the surface is significantly distorted and it does not contain any "membrane effect".

You can use other shapes for the surface, maybe a bit overlapped?
Or PFacets to also simulate a membrane effect.
Or ...

Cheers
Jan
