Dear all,
I am trying to create a random closed packing of particles with polymer interactions between the atoms. For doing this, I have first created a data file for the random closed packing of particles. The next step would be to create bonds between particles that are within a certain radius. I have used the create_bond command and bond_style command but get the error - ERROR: Incorrect atom format in data file (…/atom.cpp:892). I am not able to create bonds and am stuck here.
The interaction between the particles should be sprin glike having the form of potential energy = K(r-r0)^2 for which I have used the bond style - Harmonic.
I have attached part of my data file and lammps input script below to see if anyone is able to help.
