Flexcom provides an option to preview the water surface elevation as a function of time, before commencing a time domain finite element simulation. By default, the wave elevation is presented at the origin {Y=0, Z=0}, but any arbitrary point in the wave field may also be selected. Specifically, you can explicitly specify an alternate location via the Y and Z inputs in the Water Elevation Plot. Note that these terms are specified in the global XYZ axis system.
Note that the Water Elevation Plot operates in a synchronised manner with the relevant input data. For example, when any data pertaining to wave loading is altered in the keyword file, the plot updates automatically.
Flexcom presents a wide range of wave specification options. There are three regular wave options as follows:
•Regular Airy describes linear Airy wave theory.
•Stokes V describes Stokes V wave theory, and presents the various options for the calculation of vessel response.
•Dean’s Stream describes Dean’s Stream wave theory, and presents the various options for the calculation of vessel response.
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.
Refer to Wave Loading for further details.
The Water Elevation Plot operates like all other plots in Flexcom. For further information refer to Plotting.
