[lammps-users] Regarding multi-sphere simulation in LAMMPS

LAMMPS LAMMPS Mailing List Mirror

Dear all,

I was wondering whether a granular simulation with multisphere particles can be done on LAMMPS. Can fix rigid be used to serve the purpose? I am confused about the template to be used for the fix rigid. If I use a molecule template, it requires molecular atom_style for the fix rigid to work. But I need atom style to be spherical for granular simulation. Any suggestions?

Best regards
Saikat

I don’t think this statement is true. Can you provide a simple/minimal example demonstrating this?
