Question #678523 on Yade changed: https://answers.launchpad.net/yade/+question/678523 Chien-Cheng Hung requested more information: Hi Luc, Could you give some comments on the main difference between the internal friction angle of material and the interparticle friction angle? I couldn't find this information on the Yade. Or could you share some links with me for more detailed information?

Question #678523 on Yade changed: https://answers.launchpad.net/yade/+question/678523 jamespaul posted a new comment: Thanks Luc, I'm recreating other people's papers.The author used open-source code Lammps.He used four parameters:shear modulus,particle Poisson’s ratio, particle density, interparticle friction coefficient.This should be the simplest material.I lack knowledge of physics.The result of my simulation is somewhat different from that of the paper. So I suspect I have a problem converting the Angle of friction. I will really appreciate your concern.

Question #678523 on Yade changed: https://answers.launchpad.net/yade/+question/678523 Luc Scholtès posted a new comment: I agree with Bruno. Self validation is crucial in our "world". Just print the calculated value and compare it to the expected one :) Also, be careful not to mix up the internal friction angle of a material and the interparticle friction angle.
