Hi All,
May I ask if the Atoms-to-Continuum (AtC) user package of lammps allows for coupling of continuum fields (and continuum modeling methods) with lammps GRANULAR package?
This is not obvious from the AtC package description. At some point, it is mentioned that the coupling is only meant for thermal physics. However, AtC package seems to calculate some other continuum fields that are relevant for the granular package, so I don’t understand why in general it cannot be used for the granular model (if that is case). I appreciate any helps and advice, especially from the AtC package developers team, regarding granular-AtC coupling if possible.

Thank you.

AtC knows nothing about extended particles or their properties. the use of the term “atoms” in atoms-to-continuum should be a strong hint. the length scales are vastly different.
