Nima Goudarzi is still having a problem:
Thanks so much Jerome,

Porosity is for sure of interest but as you mentioned, I have the tools
for its calculations. My issues are at larger extent:

1- aabbwalls does not work with polyhedra therefore I am forced to use walls instead 
2- wall does not work properly as well especially in the confining phase. I have never been able to reach to the predefined  triaxial goals. Most of the time the collision between walls and polyhedra does not occur and when I reduce the time step, the analysis becomes hatefully slow. 
3- I use PSD for polyhedra  in my simulations by first generating a sphere pack following a certain PSD and then converting them to polyhedra. Also I run triaxial tests in two phases with two different scripts: in the first one I generate the sample with my desired porosity using multi-layer compaction  and export the particles (sphere, clumps, or polyhedra). I, then, import the particles in a separate script, and apply the confining presses and deviatoric loading.

In close, I have issues in box-polyhedra interaction . BTW do you by
chance have a sample of triaxial tests with polyhedra?
