Can you please tell me if I only need to find wave forces which boundary condition I should use and where I can define wave velocity? I can define wave height, length and wave theory if I select open channel wave boundary condition.nIf I am selecting velocity inlet there is a velocity option but still, I guess it's a flow velocity, not the wave.nI have followed the manual but still, I did not understand. Please refer to the attached figures if you can help me out. Thanks.nnn
