<P><B>Syntax:</B>
</P>
<PRE>compute ID group-ID rotate/dipole
</PRE>
<UL><LI>ID, group-ID are documented in <A HREF = "compute.html">compute</A> command
<LI>rotate/dipole = style name of this compute command
</UL>
<P><B>Examples:</B>
</P>
<PRE>compute 1 all rotate/dipole
</PRE>
<P><B>Description:</B>
</P>
<P>Define a computation that calculates the total rotational energy of a
group of atoms with point dipole moments.
</P>
<P>The rotational energy is calculated as the sum of 1/2 I w^2 over all
the atoms in the group, where I is the moment of inertia of a
disk/spherical (2d/3d) particle, and w is its angular velocity.
</P>
<P><B>Output info:</B>
</P>
<P>The scalar value calculated by this compute is "extensive", meaning it
it scales with the number of atoms in the simulation.
