Hi, all
I am thinking and finding if there is a rotation viscosity(damping) or rotation constraint command in LIGGGHTS, which may allow realistic description of granular flow behavior.
I have found a fix momentum command which allow me to zero angular momentum every several steps, but it is not what I want.
Any response from you will help! Thanks a lot!

There is a rolling friction
There is a rolling friction model, see the doc for pair gran. Also, you can easily write a command that applies damping to rotational motion (similar to fix viscous), if that is what you are looking for.
