dimension command :h3
|
|
|
|
[Syntax:]
|
|
|
|
dimension N :pre
|
|
|
|
N = 2 or 3 :ul
|
|
|
|
[Examples:]
|
|
|
|
dimension 2 :pre
|
|
|
|
[Description:]
|
|
|
|
Set the dimensionality of the simulation. By default LAMMPS runs 3d
|
|
simulations. To run a 2d simulation, this command should be used
|
|
prior to setting up a simulation box via the
|
|
"create_box"_create_box.html or "read_data"_read_data.html commands.
|
|
Restart files also store this setting.
|
|
|
|
See the discussion in "Section_howto"_Section_howto.html for
|
|
additional instructions on how to run 2d simulations.
|
|
|
|
IMPORTANT NOTE: Some models in LAMMPS treat particles as extended
|
|
spheres or ellipsoids, as opposed to point particles. In 2d, the
|
|
particles will still be spheres or ellipsoids, not circular disks or
|
|
ellipses, meaning their moment of inertia will be the same as in 3d.
|
|
|
|
[Restrictions:]
|
|
|
|
This command must be used before the simulation box is defined by a
|
|
"read_data"_read_data.html or "create_box"_create_box.html command.
