Re: User defined spectrum from routine UserWaveSpctrm in HydroDYn

Dear sir, Thank you for the code. I have time series data i.e. in seconds and response in meters. I have gone through the code and being new to MATLAB, as far as I understood, we have to input time series data as 'Data' and should convert it in separately into frequency and input as 'df'. If it's co...

Re: User defined spectrum from routine UserWaveSpctrm in HydroDYn

Sir,

I need to plot the Power spectral density of the responses I got using FAST for a spar model. I could not get any code or mathematical background for the same. Please guide me where I can find the mathematical expressions or a code.

Thank you

Query regarding results of semi submersible platform

Dear Mr. Jonkman, I am working on semi submersible platform combined with a point absorber wave energy converter. I have obtained hydrodata for FAST simulation through WAMIT. 1. I've done FAST analysis of that platform for 8m/s windspeed and 2.5m waveheight and I'm obtaining all the platform heave v...
