We
...
designed
...
a
...
dynamical
...
simulation
...
to
...
compute
...
the
...
particle
...
trajectories
...
as
...
a
...
function
...
of
...
time.
...
The
...
simulation
...
utilizes
...
the
...
Velocity
...
Verlet
...
algorithm,
...
which
...
calculates
...
positions
...
and
...
velocities
...
of
...
particles
...
via
...
Taylor
...
expansion.
...
Because
...
the
...
Newton’s equation
...
of
...
motion
...
is
...
second
...
order
...
in
...
relative
...
position
...
(r),
...
the
...
initial
...
condition
...
needs
...
to
...
specify
...
both
...
particle
...
position
...
and
...
velocity
...
at
...
time

0.

The

model

makes

use

of

the

following
