Here

is

code
...
I
...
used
...
to
...
process
...
force
...
data
...
for
...
my
...
swept
...
foil
...
experiments
...
and
...
for
...
forced
...
vibration
...
experiments.
...
Feel
...
free
...
to
...
modify

for

your

own

needs/chuckle
...
at

my

poor

coding

abilities.

Overview
...
of
...
what
...
you
...
need
...
to
...
do
...
to
...
process
...
force
...
data
...
:
...
Load
...
in
...
the
...
two
...
files
...
you
...
obtained
...
1)*.lvm
...
contains
...
force
...
data
...
2)
...
*.txt
...
contains
...
position
...
data
...
Calculate
...
the
...
inertia
...
forces.
...
You
...
can
...
either
...
do
...
this
...
by
...
repeating
...
your
...
experiments
...
in
...
air
...
(but
...
that
...
requires
...
draining
...
and
...
refilling
...
the
...
tank),
...
or
...
using
...
F_inertia
...
=
...
(mass
...
of
...
everything
...
below
...
the
...
force
...
sensor)
...
*
...
(acceleration),
...
where
...
acceleration
...
is
...
calculated
...
using
...
the
...
double
...
derivative
...
of
...
position
...
(from
...
the
...
*.txt
...
file).
...
This
...
file
...
is
...
saved
...
in
...
hex
...
format,
...
so
...
you
...
need
...
to
...
convert
...
it
...
to
...
a
...
read-able
...
form.
...
Calculate
...
the
...
total
...
forces.
...
Do
...
this
...
by
...
multiplying
...
the
...
6x6
...
calibration
...
matrix
...
(and
...
scaling
...
factors)
...
to
...
the
...
6
...
columns
...
of
...
force
...
data
...
(they
...
should
...
be
...
the
...
first
...
6
...
of
...
the
...
9
...
columns
...
saved,
...
if
...
you
...
used
...
our
...
standard
...
LabView
...
program
...
to
...
collect
...
data).
...
Apply
...
an
...
appropriate
...
filter.
...
Calculate the hydrodynamic forces.
...
F_hydro
...
is
...
the
...
remaining
...
component
...
of
...
F_total
...
after
...
you
...
remove
...
F_inertia.
...
Calculate
...
non-dimensional
...
coefficients
...
as
...
desired.
...
Use
...
the
...
length
...
of
...
the
...
submerged
...
span
...
in
...
the
...
calculation.
