Status: Open => Answered
Jérôme Duriez proposed the following answer:
Everything you said is correct, so I guess you almost understood stress masks, congratulations !
In order to nail it down once for all (hopefully) and understand more complex cases than the isotropic 111 = 7, let say that
stressMask = a*2^0 + b*2^1 + c*2^2 = a + 2b + 4c, with a,b,c = 0 or 1.
Then a corresponds to x direction (direction "0"),
b corresponds to y direction (direction "1"),
and c corresponds to z direction (direction "2")
and the 0/1 values tell you whether each direction is strain (0) or
And, as you said, the range of possible values for a + 2b + 4c, with a,b,c = 0 or 1, indeed goes from 0 to 7.
