<P>This fix computes a 3-vector of forces, which can be accessed by
various <A HREF = "Section_howto.html#4_15">output commands</A>. This is the total
force on the group of atoms before the forces on individual atoms are
changed by the fix. The vector values calculated by this fix are
"extensive", meaning they scale with the number of atoms in the
simulation.

<P>No parameter of this fix can be used with the <I>start/stop</I> keywords of
the <A HREF = "run.html">run</A> command.
</P>
<P>The forces due to this fix are imposed during an energy minimization,
invoked by the <A HREF = "minimize.html">minimize</A> command.
