salutations once again :) I have continued considering my problem, and have another question..
this should be easy in yade, but I can't spot the easy solution that must be there. I have beads in a container. I want to model their friction against it's walls. I can get the friction of the beads themselves by measuring the angle of internal friction. assuming I know the poissons ratio and young's modulus, I am set. but for the walls, it is a different story. is there no way to simply specify the coefficients of static and kinetic friction of the wall material? or do I have to measure the angle of internal friction of beads made with the same material? also, how do I take into account that the coefficients of friction between, say, glass and teflon, teflon and teflon, and glass and glass, are all different, for both the cases of static and kinetic friction? I feel i'm pushing it a bit, but these also seem valid questions when it is taken into account that this program operates at timesteps of e-6 seconds, and therefore necessarilly takes into account a great deel of physics. -mike --- On Tue, 7/20/10, Bruno Chareyre <[email protected]> wrote: From: Bruno Chareyre <[email protected]> Subject: Re: [Yade-users] hello? -help with a spinning bucket!

It is just a "bool" in most cases. ;-) You add it to a class to switch between different behaviours, for instance. We also tend to call class members "attributes" these days (python influence).
