*WAVESO

Data format:

One line with 9 parameters

IOP PER HS IOP1 TMINLF TMAXLF TMINHF TMAXHF NS

Status :

Optional

Restriction :

Only in dynamic analysis with irregular wave spectrum.

Purpose :

To generate second order waves loads for pipe loading (if IOP1=0) or generate second wave loads through first order spectra.

Details :

Parameter	Description
IOP	Flag used to select the terms that shall be accounted for: - If IOP = 0: Both low and high frequency terms (wi-wj) et (wi+wj) are accounted for - If IOP = 1: Low frequency terms (wi-wj) only are accounted for - If IOP = 2: High frequency terms (wi+wj) only are accounted for
PER	Percentage used to remove some components (removed if A(i)A(j) < perMAX(A(i).Aj) where A(i) and A(j) are the amplitudes of the components at frequncies wi and wj
HS	Value of global Hs of the generated wave
IOP1	IOP1=1: second order wave is entered as first order spectra (and then use first order wave loads in a hydrodynamic database for instance)
TMINLF	Value of minimum period for the second order low frequency spectrum (if activated by IOP flag)
TMAXLF	Value of maximum period for the second order low frequency spectrum (if activated by IOP flag)
TMINHF	Value of minimum period for the second order high frequency spectrum (if activated by IOP flag)
TMAXHF	Value of maximum period for the second order high frequency spectrum (if activated by IOP flag)
NS	Number of spectra to define the second order wave (The first order wave is defined by one spectrum. If IOP1=1, the second order wave components created by the first order spectrum are computed and ordered based on their amplitudes. Then NS low frequency spectra and NS high frequency spectra are created depending on the value of IOP. Each spectra has the same number of components as the wave frequency spectrum.)
