Syntax:
dimension N
Examples:
dimension 2
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 or read_data commands. Restart files also store this setting.
See the discussion in this section for additional instructions on how to run 2d simulations.
Restrictions:
This command must be used before the simulation box is defined by a read_data or create_box command.
