[lammps-users] computing total energy of carbon nanotube system

Dear all,
Hi I am new to lammps.I want to know whether is it possible to compute the total energy of a double walled carbon nanotube system with an atom count of around 3000. My main theme is to find the minimum of potential energy in the system and the interaction forces.If it’s possible to do with Lammps any procedure to do so would be gately helpful.

Thank you

Kind regards,
