Dear Lammps users,
I am trying to get a cross link between two nanotubes, to get this I have generated a random carbon atom between the tube. Now i need to form bond between this random atom and adjacent atom of the tube.
I used fix 3 all bond/create 10 1 10 1.5 1 command to create a bond between these atom but I am getting a message of Unknown fix style.
Did I make some mistake or can I use another approach to form cross links.
