Figure 10. Wave Generator Properties dialog
On the left side of the dialog, the user selects the type of wave to be generated. This can be regular,
irregular unidirectional, or irregular multidirectional wave type. Then the user specifies whether the
time series will be synthesized from wave parameters or read from a file. If synthesized, the
parameters (wave height, period, and direction) are entered in the spreadsheet on the right side of the
dialog under Spectral Parameters.
(1) Regular waves. When generating regular waves the following parameters must also be
specified:
Wave height
Wave period
Number of wave cycles
Wave direction
(2) Irregular unidirectional waves. Irregular unidirectional waves can be generated in the fol-
lowing ways:
By using an input water-surface elevation time series file (*.ts1). The user specifies
which *.ts1 file to use and incident wave direction. The wave direction can either be specified in a
shore normal/local coordinate system or a meteorological/global coordinate system.
By creating a synthetic water-surface elevation time series from an input wave frequency
spectrum file (*.spf). The user specifies which *.spf file to use and incident wave direction, time
series duration, and random number seed.
By creating a water-surface elevation time series from a parametric wave spectrum listed
in Table 5. The user also has to specify incident wave direction, time series duration, and random
seed.
