Wave spectrum file
An input file containing the components to a
Wave spectrum
can be imported into Ashes. This is useful when you want to define your own deterministic irregular wave elevation (as opposed to defining an irregular wave elevation by specifying the
significant wave height
and the
spectral peak period
, see
Irregular waves
).
The wave spectrum file contans the keyword
Irregular waves components
, followed by a table that defines each of the wave components that compose the spectrum. Each component is defined by four values:
- the period in seconds
- the wave heigh t in meters
- the phase angle in degrees
- the direction with respect to North in degrees
The figure below shows an example of the file:
More information about the components of the spectrum can be found in the theory manual, in the
Wave spectrum input file
section.
