Hi Nejib,

There is written somewhere in the engine:

height0 = height; depth0 = depth; width0 = width;

If this line is not commented, you will have only the strain increment 
developed during the current simulation. If you want the total 
deformation, you just need to comment this line.

 Luc

I think that depends on
