In this paper, the theory of progressive ocean-surface
gravity-waves is discussed, followed by the concept of the
representation of the irregular sea-state by a sea-spectrum.
Fourier series decomposition of the irregular sea-surface
into its constituent regular waves and the method of realizing
unique time-records of the sea-surface-elevation
from commonly used sea-spectra is described. A detailed
description of the development of Modelica componentmodels
to generate regular as well as irregular waves, and
depth-varying current, with an eye on the requirements
imposed by probable integrated simulation scenarios, is
then presented and the results discussed.
