[lammps-users] Bond atoms missing!

Hi all,

I am trying to set polymer fluid flow in a channel. Following the instructions
in the LAMMPS manual and with the help of LAMMPS users I developed a
input script. But I could not run the simulation, it ends up saying " Bond atoms missing ".
I know this has to do something with the overlapping of the beads. I tried equilibrate it for long, used
smaller time steps and even used the minimized the energy but with no success.
Here is the script and relevant files needed to run this simulation.
If anyone can tell the precautions to be taken while simulating polymers, it will be great.

Enjoy your easter!!

Thanks in advance
