New question #198594 on Yade:

I'm not sure how to determine the property for material.
After I read the message:
-----
class yade.wrapper.ElastMat(inherits Material → Serializable)
Purely elastic material. The material parameters may have different meanings depending on the
IPhysFunctor used : true Young and Poisson in Ip2_FrictMat_FrictMat_MindlinPhys, or contact
stiffnesses in Ip2_FrictMat_FrictMat_FrictPhys.
poisson(=.25)
Poisson’s ratio or the ratio between shear and normal stiffness [-]. It has different meanings
depending on the Ip functor.
young(=1e9)
elastic modulus [Pa]. It has different meanings depending on the Ip functor.
-----
Is Ip2_FrictMat_FrictMat_MindlinPhys use E,v as normal Poisson's ration and elastic modulus as in pfc3D?  And  Ip2_FrictMat_FrictMat_FrictPhys use E,v as kn/ks and E for what?
Thanks
