That is super easy, use excel or write code in matlab to generate CNT bundle XYZ file from a single CNT XYZ coordinate file. If need help, let me know.
I want to have a bundle of four CNT (as attached) that should be periodic in x-y plane. but nanotube modeler didn't give me the dimension of the simulation box.
could you please guide me?
do you have the code that you said? if yes, please share with me.
