wangxiaoliang is still having a problem:
I agree with Jakob, makeCloud can either have an exact psd curve with inexact porosity OR an
exact porosity with inexact psd curve. But it is far from the true triaxial test in lab.

I think we need at least some of the features agree with true triaial
sample before any loading( isotropic or shearing)

1, psd agreement
2, porosity
3, particle shape ( some, maybe not ok now)

if not, how can u compare your numerical results with experiments, or it
is just a mathematical game?

And how can you say your sample is dense or loose?

As I know, tutorial in "session1" can't solve my questions.
