Christian Jakob proposed the following answer:
Hi,


If you use makeCloud() it is recommended to call

O.bodies.updateClumpProperties()

It will correct volume/masses/inertia of clumps [1].


If you use TriaxialStressController() you get the porosity [2] very cheap via

triax.porosity

I updated the code, so that clumps volume is considered correctly.


Another tool is 

voxelPorosity()

It can also be used for your purpose [3], but every call costs a little
bit computation time...


Hope it helps,

Christian
