Question #641979 on Yade changed:
https://answers.launchpad.net/yade/+question/641979

    Status: Open => Answered

Jérôme Duriez proposed the following answer:
It's not really a matter of confusion between 1,2,3 vs x,y,z (by the
way, what is confusing with 1=x, 2=y, and 3=z ? ;-) ) but a matter of
how stressMask works.

You said you want "strain-controlled for direction1, and stress control for direction 2 and 3", then you do not have any other choice than using 
stressMask 
= 0 *2^2 (for direction 1) + 1*2^1 (direction 2) + 1*2^0 (direction 3)
= 3 !

Thank you Gary ;-)
