Dear LAMMPS users,
I have a coarse-grained molecular system including 2 bead types. I firstly create a pure coarse-grained polymer system with only one bead type and carry out a relaxation. Then I want to randomly add CNT coarse-grained molecules in this pure polymer model, but I got the error message: Invalid atom type in create_atoms mol command.
I’ve read the document of read_data and create_atoms several times but I still miss the problems, and here is part of my input file:
boundary p p p
read_data polymer.data extra/atom/types 1 extra/bond/types 1 extra/angle/types 1 extra/dihedral/types 1
molecule cnt data.cant offset 1 1 1 1 0
create_atoms 4000 random 21 85526 NULL mol cnt 27957
And the data file of polymer and CNT only contain one type of atom, bond, angle and dihedral, respectively. I wonder where is problem I missed. I would really appreciate any advice because I am a bit confused. Thank you so much in advance.
