<P><B>Description:</B>
|
|
</P>
|
|
<P>Specify the orientation of a cubic lattice along simulation box
|
|
directions <I>x</I> or <I>y</I> or <I>z</I>. These 3 basis vectors are used when the
|
|
<A HREF = "create_atoms.html">create_atoms</A> command generates a lattice of atoms.
|
|
</P>
|
|
<P>The 3 basis vectors B1, B2, B3 must be mutually orthogonal and form a
|
|
right-handed system such that B1 cross B2 is in the direction of B3.
|
|
</P>
|
|
<P>The basis vectors should be specified in an irreducible form (smallest
|
|
possible integers), though LAMMPS does not check for this.
