Hi,

Sorry for the basic question, but I see waveVelocity/waveAlpha are commented out in some of the waves2Foam tutorial cases (waveFlume, 3Dwaves etc) and when I run them zeroGradient is selected.

I am just wondering if there is any documentation, report or publication about the differences between zeroGradient and waveVelocity/waveAlpha (for U and alpha) BCs when used in conjunction with waves2Foam relaxation zone technique?

Many thanks for your help.

Hi sinah


Did you find the answer? I have the same doubt.
