Hi all,
As we all know, neighbor cutoff = force cutoff+skin. However, I don't know how LIGGGHTS determines the force cutoff value.
Are there any command in LIGGGHTS that we could use to modify force cutoff (haven't found anyone yet)?
Best regards,
Su

Hi Su,
Hi Su,
for granular simulations, the force cutoff is the sum of the particle radii in contact. For a polydisperse simulation, the maximum particle radius is taked into account
Best wishes
