hello , how to compute the volume of the system or the group atoms,
and the default vol in the thermo_style command is just the volume of
the global simulation box, isn't it. when i use the periodic boundary
the volume is the same ,isn't it.
thanks
Thermo vol is the volume of the entire box. The volume
of a group of atoms isn't well defined and LAMMPS doesn't
currently attempt to calculate it. If you can figure out a
precise definition of what you want, you could write a compute
to do it.
