Hello everyone,

I am building the 3D NWT based on our lab tank, I am using the flap wavemaker and 3Dwaveabsorption in olaFLow currently. The generation is accurate and perfect. However, the reflection from the absorption boundary is obvious.

I read the paper On the Assessment of Numerical Wave Makers in CFD Simulations by Windt, and know that the Numerical beach maybe the best option. But I didn't find any case for that.

Can anyone share some cases of the numerical beach in OpenFOAM or any other better absorption methods??

Thank you very much.
