thank's for the tip :-D I will look into that in more detail, and get back to you if anything escapes me. :)
for the behavior I expect, I expect the beads to 'glue' themselves to the walls of the rotating container, ultimatelly forming a hollow cone in the middle of the container for the case of small particles and high rotational velocities. I would ultimately like to simulate 1mm^3 particles in a 1 litre cylinder, rotating at up to 5000 rpm. see this paper for an example: http://www.sciencedirect.com/science?_ob=MImg&_imagekey=B6TVK-4B3NPS4-1-56&_cdi=5537&_user=6937534&_pii=S0167278903003087&_orig=search&_coverDate=01%2F15%2F2004&_sk=998119998&view=c&wchp=dGLbVlz-zSkzV&md5=c05f264e2e48c8f39add03781993896a&ie=/sdarticle.pdf and you leave me wondering.. would these high velocities necessarilly mean that I would need an even smaller timestep than has already been stated that I need? It seems so small already, I would be inclined to doubt it.. cheers, -mike :) --- On Thu, 7/8/10, Sergei D. <[email protected]> wrote: From: Sergei D. <[email protected]> Subject: Re: [Yade-users] hello? -help with a spinning bucket!
