Granular systems

Dear all

I have two question:

  1. I want to simulate a system with two type of particle. Is it possible?If yes, how do I determine radius of particles?
  2. Is it possible that we have 6 reflective walls in granular system?

Kind regards,
Meisam

Dear all

I have two question:
1) I want to simulate a system with two type of particle. Is it possible?

yes and no. the decisive question is, how would these particles differ?

If yes, how do I determine radius of particles?

radius is a per-atom property when using atom_style
sphere as required by granular pair styles.

2) Is it possible that we have 6 reflective walls in granular system?

yes, why not? mind you, reflective walls only invert the
velocity of the center of mass of a particle, they have
no knowledge of additional properties of granular particles.
