TDiffractionWaveComponent

The TDiffractionWaveComponent structure is used to store information about a single wave component. This information is returned from C_GetDiffractionWaveComponents.

typedef struct {

double Frequency;

double FrequencyLowerBound;

double FrequencyUpperBound;

double Amplitude;

double WaveNumber;

double Direction;

} TDiffractionWaveComponent;

Members

Frequency

The frequency of the wave component.

FrequencyLowerBound, FrequencyUpperBound

For a random wave, the component represents a frequency interval. The FrequencyLowerBound and FrequencyUpperBound fields define this interval. Otherwise (i.e. in the case of user-specified components) then these fields are set to OrcinaUndefinedReal().

Amplitude

The amplitude of the wave component.

WaveNumber

The wave number of the wave component. This is defined as 2π / L where L is the wave length for this component.

Direction

The direction of the wave component measured in degrees, relative to the sea state direction during an OrcaWave drag linearisation calculation.
