This is an alternative, approximate parameterisation of the JONSWAP
spectrum, in which the significant wave height and period are specified
instead of the wind speed and fetch.
Example specification, in constant/waveProperties:
waves
(
irregular
{
spectrum GodaJONSWAP;
Hs 2; // <- significant wave height [m]
Ts 6; // <- significant wave period [s]
n 12; // <- number of samples []
angle 0;
}
);
