Hi José,

Stresses, strains are printed in a text file during computation (default 
name "WallStresses", you can define a different name in the interface).

The generation of balls is made after line 271  of TriaxialTest.cpp :

vector<BasicSphere> sphere_list;
message=GenerateCloud(sphere_list, lowerCorner, upperCorner, 
numberOfGrains, 0.3, 0.75);
vector<BasicSphere>::iterator it = sphere_list.begin();
    vector<BasicSphere>::iterator it_end = sphere_list.end();
           
    for (;it!=it_end; ++it)
    {
        cerr << "sphere (" << it->first << " " << it->second << endl;
        createSphere(body,it->first,it->second,false,true);
        rootBody->bodies->insert(body);
    }


This result in a uniform ditribution between min and max radius (I just 
realized that min/max radii are hardcoded here, they should be included 
in the interface to be modified without the need of recompiling).
For the moment you will have to modify those lines and

There is something written I think. You should checkout the SVN 
repository and look for a "doc" directory (it is a very old version, but 
basic concepts should be there).

Also, I'm sending you a journal paper (unpublished yet) in a separate email.
