Banded white noise simulation

Postby Tomas.Cortes » Wed Jun 26, 2019 6:44 am

Hi everybody,

Does anyone know how to set up the load case 2.6 in hydrodyn file? I see where I can set the white noise option (WaveMod) but not the frequency range and the PSD specified...

Thanks in advance,

Dear Tomas,

Select WaveMod = 3 to enable a white-noise spectrum. The lower and upper cut-off frequencies are set via WvLowCOff and WvHiCOff. The magnitude of the PSD within this frequency range is determined by WaveHs.
