Dear all,
I want to generate a linear wave in fluent, However there are some problems.
My case is as follows:
model: 4m(L)*0.45m(H) in 2D case.
water depth: 0.3m
wave height: 0.02m
wave period: 0.6s

I tried in fluent with laminar model, it can work fine.
However, when I switch to turbulent (k-e or k-o) model, the wave patten is no longer sinusoidal, and become irregular. Even, the wave will decay quickly.

Any one knows what is the problem?
Should I just use laminar model?

Thanks for your kindly help,
