Hi,

https://yade-dem.org/doc/yade.wrapper.html?highlight=interaction%20detection#yade.wrapper.Ig2_Sphere_Sphere_ScGeom.interactionDetectionFactor
Here gives a parameter that create interaction range for particle packing, but I have no idea on how to determine this parameter ?
Because in this paper (A DEM model for soft and hard rocks: Role of grain interlocking on strength), it was stated that if Rmax/Rmin=2, interactionDetectionFactor must not be larger than 1.5.  In my simulations, Rmax/Rmin=9, thus, I have no idea to determine the interactionDetectionFactor. I have tried interactionDetectionFactor=1.5 to do some simulations, it got a relatively good result. But this selection (interactionDetectionFactor=1.5) seems go against the theory put in that paper. 

Can anyone help me solving this confusion ?

Thanks in advance,

Huihuang
