Ok Thank you Jerome and Bruno,

Ok, it may be needed to adapt the TT prepocessor but I imagine that is 
not a big job. About the box-box interactions, I don't need it. So it 
should be ok.
You can guess what I want to do: I want to perform a stress control, but 
without a closed loop-control as it is done in the 
TriaxialStressController, but by applying directly forces on walls. I 
know it is less efficient than a close loop control, but... I need it.

Thanks, Luc
