I am currently using ANSYS Fluent to simulate regular waves, such as Stokes first and second-order waves, as well as Airy wave theories. While I have input parameters like water depth, wavelength, and wave height, the resulting surface elevation versus time plot does not appear as a regular wave. Instead, it shows unusual peaks and troughs, which differ significantly from the expected wave behavior. I suspect this irregularity may be due to the absence of a specified wave period in my setup. Unfortunately, I could not find an option to directly input the wave period in ANSYS Fluent. Could you please advise if the wave period is crucial for generating regular wave patterns and how I can correctly input it in the simulation settings? Any guidance would be greatly appreciated.

The panel will contain everything, typically it's a wavelength and you set the speed in the first tab of the bc panel. If you're not seeing "good" waves check the mesh is refined sufficiently in both amplitude & wavelength and that the sky is a pressure boundary at a reasonable distance from the free surface.

I couldnot find an option to enter wave period in Boundary Conditions
I exactly followed procedure from an article and also used same values as input parameters(except wave period), but I could not able replicate the same result, the waves are not looking like regular waves

Check the Theory Guide - wave frequency is derrived from the wavelength via the Wave Theory setting.
