Piston JONSWAP Peak

lhanley222

Hi There,

Does anyone have any idea on how to make the the peak of the JONSWAP higher while maintaining wave parameters for an irregular piston motion? I am trying to roughly simulate some field results for my project, but the spectrum generated from the SPH piston has a much lower peak and more spread. I've looked at the discretization options but those do not change the shape of the spectrum. And I know that the Pierson Moskowitz should probably have an even lower peak. I'd like to look into using some wave coupling techniques in SPH but I think I don't have the time and want to keep things simple.

Thanks

Alex

@iarba27 can explain this better to you

Thanks Alex,

I was able to tune up the JONSWAP Peak Coefficient and got something closer to what I wanted. Maybe Corrado has more insight.
