|

|
|
<P>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
|
||
|
|
<A HREF = "create_box.html">create_box</A> or <A HREF = "read_data.html">read_data</A> commands.
|
||
|
|
Restart files also store this setting.
|
||
|
|
</P>
|
||
|
|
<P>See the discussion in <A HREF = "Section_howto.html">this section</A> for additional
|
||
|
|
instructions on how to run 2d simulations.

<P><B>Restrictions:</B>
|

</P>
|
||
|
|
<P>This command must be used before the simulation box is defined by a
|
||
|
|
<A HREF = "read_data.html">read_data</A> or <A HREF = "create_box.html">create_box</A> command.
