The Wave Spectrum Plot provides a useful graphical preview of a wave spectrum, before embarking on a 3-hour time domain simulation of a random seastate. Spectral Density is plotted as a function of frequency for any wave spectrum defined in the input data. If more than one wave spectrum is included in the input data, the name of the desired spectrum may be selected from the Plot drop-down list.
Note that the Wave Spectrum Plot operates in a synchronised manner with the relevant input data. For example, when any data pertaining to wave spectra is altered in the keyword file, the plot updates automatically.
Flexcom presents a wide range of wave specification options. There are five options for defining a random seastate in terms of a wave spectrum, as follows:
•Pierson-Moskowitz describes the Pierson-Moskowitz wave spectum model, and presents the various formats for input data specification.
•Jonswap describes the Jonswap wave spectum model, and presents the various formats for input data specification.
•Ochi-Hubble outlines the Ochi-Hubble wave spectum model.
•Torsethaugen outlines the Torsethaugen wave spectum model.
•User-defined describes a facility whereby you can input an arbitrary wave spectrum directly in terms of a series of data pairs.
