Hi there again,
You can find the answer in the great book "Wavess in oceanic and coastal waters" " by Leo H. Holthuijsen (I believe is in page 44 a clear explanation).
Best,

Hi ulgenk,
Unfortunately we have not released the code of waves+currents.
Please, send me a direct message if you might be interested in a potential collaboration.

Hi Ben,
If it is a restart, you do not need a ramp time.
The rampTime filter was created to be able to replicate what happens in laboratory, where first waves are normally filtered.

To describe the three-dimensional, moving waves, we use the random-phase/amplitude model (in x, y and t-space) by considering the sum of a large number of propagating harmonic waves in...

Hi Baptiste,
Yes, always the best choice is to rotate your object, as the wave paddle absorption implemented can just deal with the perpendicular incoming waves to the patch.

Hi Ali,
This numerical approach is wrong. Please, try to validate with some laboratory data ( Kemp&Simmons [1982] or Umeyama [2005]) and you will see that it does not work.
