Which assumptions can we place for water surface wave simulation?
Incompressible and Irrational
div u = 0
curl u = 0
small motions only
boundries infinitly far away
air pressure constant
Fourier analysis gives closed-form solution for wave height 𝜂
Explain the variables occurring in the wave solution to the water wave equation!
Is the wave number of a wave with large wavelength high or low?
low
Are low-frequency waves or high-frequency waves mainly driven by gravity?
low frequency waves
How does the wave speed 𝑐𝑝 depend on the spatial location 𝑥?
it depends on the height at position x
Explain the trochoidal wave model!
not only up and down movement, but also horizontal (particles move along a circle)
Why is it better to simulate based on amplitude and phase, rather than the wave height directly?
can be done at lower resolution, disconnect render and simulation resolution
How do wave packets extend upon wave particles?
they are more phisically grounded (correct wave speed, refraction, correct group speed)
