<P>This fix computes a scalar energy and a 6-length vector of forces (one
force magnitude per wall), which can be accessed by various <A HREF = "Section_howto.html#4_15">output
commands</A>. The scalar and vector values
calculated by this fix are "extensive", meaning they scale with the
number of atoms in the simulation. Note that the scalar energy is the
sum of interactions with all defined walls. If you want the energy on
a per-wall basis, you need to use multiple fix wall commands. The 6
vector quantities are the force on the <I>xlo</I> wall, the <I>xhi</I> wall,
<I>ylo</I>, <I>yhi</I>, <I>zlo</I>, <I>zhi</I>. These values will only be non-zero if the
corresponding wall is defined. Note that an outward force on a wall
will be a negative value for <I>lo</I> walls and a positive value for <I>hi</I>
walls.
