Hello all,

Currently in Ig2_Box_Sphere_ScGeom, sphere-box contacts are seen as 
contacts between the sphere and another sphere twice bigger (the big one 
representing the box).
I'd like to change that and make the fictious sphere the same size as 
the real one, so that box-sphere contacts will have the same stiffness 
that contacts between equal spheres (preserves somehow a symetry, I 
never knew why this factor 2).

Please let me know if this change would create problems for you, and/or 
be prepared to see a small change in the rigidity of the boundaries in 
the triaxial test.

Bruno
