create_box command :h3

[Syntax:]

create_box N region-ID :pre

N = # of atom types to use in this simulation
region-ID = ID of region to use as simulation domain :ul

[Examples:]

create_atoms 2 mybox :pre

[Description:]

This command creates a simulation box that encloses the specified
region.  Thus a "region"_region.html command must first be used to
define a geometric domain.  If the region is not of style {block},
LAMMPS encloses it with a rectangular simulation box.

The argument N is the number of atom types that will be used in the
simulation.

[Restrictions:]

An "atom_style"_atom_style.html and "region"_region.html must have
been previously defined to use this command.

[Related commands:]

"create_atoms"_create_atoms.html, "region"_region.html

[Default:] none
