New question #238696 on Yade: https://answers.launchpad.net/yade/+question/238696
Hi, all, About 15 years ago, a girl did an impact experiment of a boulder impacting onto a soil layer, now I want to reproduce her experiment by using yade. The problem is that her soil layer is quite big, to respect the reality, the numerical sample will have millions of particles, and the time step will be as small as 1e-8, thus the sample might never be prepared by gravity deposition. So my question is: how could we increase the time step while not change the physics? I did some two particles impact tests, it turns out playing with radius and density (keep mass constant) could increase time step, but the contact forces will also be changed, not good. So, any other ideas? Second question: Does somebody use viscous damping of Law2_ScGeom_MindlinPhys_Mindlin()? This contact law is said to be mature, but is it proper to be used in dealing with dynamic problems? Thanks. Regards.
