A type of Waves

Properties

DirectionOfApproachClockwiseFromNorth: number (rad), optionalcoming soon

The bearing from which waves arrive at the turbine.

RandomNumberSeed: integer, optionalcoming soon

A arbitrary integer used to generate a realisation of the irregular waves. This ensures that the 'randomness' is consistent from simulation to simulation.

WaveDiffractionApproximation: object (a type of WaveDiffractionApproximation), optional coming soon

The definition of wave diffraction approximation options to account for diffraction effects at small wavelengths comparable to the size of the structure .

Can be any of the following types:

AdditionalConstrainedWave: object(AdditionalConstrainedWave), optionalcoming soon

The definition of additional constrained wave options to include a prescribed extreme wave at a particular time.

WavesType: stringcoming soon

Defines the specific type of Waves model in use. For a JonswapPiersonMoskowitz object, this must always be set to a value of JonswapPiersonMoskowitz.

SignificantWaveHeight: number (m)coming soon

The average height of the highest one third of the waves in the seastate.

SpectralPeakPeriod: number (s)coming soon

The period of the most energetic component in the wave spectrum.

Peakedness: numbercoming soon

The width of the frequency band containing most of the energy in the spectrum. It should take a value between 1 (Pierson-Moskowitz) and 7.
