Hi Nankam Brice

The relation of dispersion is correct for first order wave. for the fifth order wave, you need to find another relation of dispersion. I tested the star in the first-order wave and its results follow up dispersion relation.

In addition you can see this article or star tutorial in VOF Waves Formulation subject.

Hello Mohammad Hossein Rasti

thank you for your answer.

I did the research with your Documentation produce by Fenton, and i find the same results as Star.

Thanks again.

Hello, Nankam Brice.

I have a question about the options of current and wind.

From dispersion relation, "c" can be figured out by "c=w/k".

So, what is the difference among c, current and wind?

Waiting for your answer, thanks.

Hi Yujin Lu

In star ccm+ wind is a speed of light flow and current is a speed of heavy flow. so, in dispersion relation used current speed.

Hi, Mohammad Hossein Rasti .

Thanks for your answer.

However, in first order Stokes wave, when the current and wind speed are zero, the wave can be generated successfully in star ccm+. So, in my opinion, the current and wind speed options are not significant in first order, because the current speed can be calculated by dispersion relation. If wavelength and water depth are known, then wave speed c is also clear.

What do you think?

Hi Yujin Lu

I apologize for the late reply. when you set a current velocity as zero its mean that you defined a wave as a standing wave.

Hi, Mohammad Hossein Rasti

Sorry for late.

Briefly, when the wave length is 20m, wave height is 1m, and the wave depth is 10m, how to set the wind and current?

Thanks
