Regular wave types

Four types of regular wave can be chosen:

Airy: the wave elevation and particle kinematics is based on the linear Airy theory.
5th order Stokes: the wave elevation and particle kinematics is based on the Stokes 5th order wave theory.
Dean's Stream Function: the wave elevation and particle kinematics is based on Dean's stream wave theory.

Note

Implementation of the Stream function is based on the method developed by Rienecker and Fenton (1981). See references for details.
Automatic choice: The wave model will be automatically selected between the Airy, Stokes and Cnoidal theory, depending on the wave amplitude, period and water depth.

Note

It is recommended that you use the Dean's stream wave theory rather than Stokes 5th order theory to properly model non-linear waves. The order of the Stream function shall be set high enough to properly account for non linear effects.

Whatever the wave type you have selected, you will have to define the following wave characteristics :

Heading: direction of propagation (so-called 'to' direction). Counted positive from the X axis towards the Y-axis (in degrees),
Height: double amplitude* of the wave component - crest to trough (m),

Note

In fact for real waves the crest and trough heights are not the same, and Stokes and other theories reflect this.
Period: the wave period (in s),
Phase: phase at origin (degrees).
Stream function order (only required for Dean's stream function): the order of the Stream function.
