Hi all,
recently, I have read some papers using Yade or SDEC simulating triaxial
test over sand, and made good calibration over the dem model with experimental
models.
However, two questions puzzled.

Hi,
First, you should know that size does not matter in YADE, or, at least,
should not. Indeed, interaction laws (at least, the basic ones like

Hi Wangxiaoliang,
The closer you get to the physics of the real material with your
numerical model, the easier the calibration should become, up to the

thanks, all of your answers are helpful to me.
I know that now if is impossible to derive macroscopic behavior from

Hi,
May be it would take you a lot of time to adjust your DEM parameters to
reproduce an identical fingerprint of given natural sand (which is
