Hello everyone, I am building the 3D NWT based on our lab tank in OpenFOAM, 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 may be the best option. But I didn't find any accessible case for that. Can anyone share Any cases of the numerical beach in OpenFOAM or any other better absorption methods??
