Question #210907 on Yade changed: https://answers.launchpad.net/yade/+question/210907
Luc Scholtès proposed the following answer: OK, so the problem is more general that just "rolling moment related" as I supposed it was... Maybe you should open questions for each problem because it is difficult to see where exactly is your point. Moreover, each of them is susceptible to interest YADE users ;-) I see 2 distinct problems from your previous questions: 1 - Do we consider initial porosity as the one obtained without confinement or the one corresponding to the isotropic state pre- compression? Good question I would say... I would also say that it is difficult to generate an homogeneous sample using DEM without confinement, and I think (guys, tell me if I am wrong) that in most cases, when DEM users talk about initial porosity, it is the one obtained under isotropic confinement (the lowest confinement if you plan to run a series a triaxial compressions). BTW, is there a big change in the porosity of your real specimen when you go from 0 to 50kPa confinement? 2 - Is there any problem with rolling moment law? Why rolling stiffness does not impact my macroscopic result? If this one is actually of concern, maybe have a look to triax-cohesive.py as suggested by Bruno.
