Regular wave
Regular wave
Angle
The angle between the direction of the waves and the north direction. For example, an angle of 90 degrees leads to the waves coming from the east direction.
- Default value: 0
- Unit: $°$
- Range: -360 — 360
Height
The wave height of the regular wave.
The wave height cannot be greater than half the still water depth, nor can it be greater than what gives the maximum wave steepness of 1/7. If the Height parameter is set to a greater value it is autocorrected to the maximum allowable value.
- Default value: 5
- Unit: $\text{m}$
- Range: 0 — 100
Period or length based
Choose if the wave period or wave length should be specified. If you choose 'Wave period based' then the wave length is calculated from the period, and vice versa.
Options:
Wave period based (default):
The wave length is calculated from the period.
Wave length based:
The period is calculated from the wave length.
Period
The wave period of the regular wave.
This parameter is not shown if the Period or length based parameter is set to Wave period based in which case the wave length is calculated from the period.
- Default value: 10
- Unit: $\text{s}$
- Range: 0.1 — 1000
Length
The wave length of the regular wave.
This parameter is not shown if the Period or length based parameter is set to Wave length based in which case the wave period is calculated from the length.
- Default value: 100
- Unit: $\text{m}$
- Range: 1 — 10000
Phase angle
The phase angle given in degrees. A phase angle of 0 means that the wave surface initially has 0 elevation at the origin. A phase angle of -90 or 270 degrees means that the origin will be below the crest of the wave, while 90 degrees places it above the through.
- Default value: 0
- Unit: $°$
- Range: -360 — 360
