It has been seen that a standing wave can be initialised at the interface
between two fluids. This can be done for a chosen wavelength and
wave amplitude using the natural density gradient,
correct for the values of 
being used.
This method of initialisation does not require
that any velocities or a frequency are imposed on the wave. This means that
any measured quantity has arisen solely from the wave motion. Many standing
waves have been simulated for different values of the wavelength 
,
the gravitational strengths 
and 
, the density ratio f,
the viscosity 
and the interface thicknesses l. The viscosity is varied through the
relaxation time 
and the interface thickness is
varied through the interfacial energy 
.
The measured frequencies, damping constants and velocities were
compared to the theoretical predictions.
All the results
for the frequency were found to be in good agreement
with the theory; the damping constant was also seen to be in good agreement with the theory over a range of values where the theory is applicable.
The measured velocities were also seen to agree well with theory.
