[Bruno Chareyre <bruno.chareyre@xxxxxxxxxxx>]

More precisely, it is in TriaxialStressController. This engine needs to 
be assigned 6 boxes (one for each boundary). The boxes are used to 
define the surfaces (since you need a surface to define a stress).
If you don't have 6 boxes, you need to find a workaround.

The algorithm is : displacement = (stress offset) / (total box-spheres 
stiffness)
