granular system parameters

Hi Oksana,

I am one of the people who have used xmu > 1 as in some simulations I ran I wanted to make sure that there is no sliding (frictional slippage) between particles and set it to a huge number. But it is true that in most cases xmu < 1 .

Best wishes,


Dear George,

Thank you again. So if I need to fix my granular system by frictional forces I can set xmu larger than 1? And theoretically even spheres can be prevented from sliding?
