Hello Rob,

Thank you for the reply. 

I have reduced the numerical beach to 2 and 4 wavelengths from the outlet in some of previous simulation cases but there was still damping so I thought that the damping may be due to reflection from outlet so I increased the numerical beach length to 10 wave lengths from outlet. But even it did not helped.

I have also increased grids to 30 cells per wave height and aspect ratio of 1 in previous simulation cases but damping was present in every cases.

For the resolution, I have tried various cases T/100,T/200,T/300, T/500 and T/1000 where T is time period. But it did not helped me.

Can there be any spots in setup where I may be missing?
