Question #403385 on Yade changed: https://answers.launchpad.net/yade/+question/403385
Bruno Chareyre proposed the following answer: Hi, Short answer: There is indeed no simple relationship between ks/kn and the material parameter called Poisson, but a dependency does exist (with both the solid phase Poisson coeff. and bulk scale Poisson) hence the conventional name. Longer answer: Since material parameters and interaction parameters in Yade are independent things (different functors will lead to different dependencies) it is not realistic to expect a physical consistency of the naming. In the end the parameter "Poisson" is just a value, it doesn't have to be ks/kn - only some particular functors may really use it to define ks/kn. Besides, I can't follow you on the question "Can we set a geometry which lead to macro parameters the same as micro ones?" If a particular micro-macro relationship (e.g. equality, in your case) exists the it should hold independently of the geometry of the specimen, else it is a physical aberration. So geometry is obviously not the right button to push to solve your problem.
