Re: hello? -help with a spinning bucket!
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:
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..

I do not know what behavior you expect and what the interaction law using, but just in case, do you aware about differencies in behaviour with cundall and viscoelastic damping for a dynamic simulation? see, for example, scripts in examples/dynamic_simulation_tests
and yes, you have very fast velocities, so you need very tiny dt...
