Open kim

can we use open kim to define interatomic potential for (polymer + water ) system ?

Hi Sachin,

Unfortunately OpenKIM does not yet support the bonded force field models that are typically used to define such interactions. We are actively working on that functionality, though, so keep an eye out for that update!

Cheers, ilia

Thanks sir…
Bond coeffiecient, Angle coefficient, Dihedral coefficient we have to define manully using bond_style,
angle_style,dihedral_style command in LAMMPS?
Is there any alternate option to define forcefield parameter ?
