Rolling friction

I want to add the rolling friction model into DEM. Does the mix consider the rolling friction?

You can add it in cal_force_dem.f

Also remember to modify the calc_collision_wall_mod.f file to add the rolling friction

yes, I have done it. Thank you

Hi Yue yuan He,
I also want to include the Rolling friction model in my model. Could you tell me how in cal_force_dem and calc_collision_wall_mod did you implement it , so I can compare it to my version ?

Thank you,
best Janna
