I'm going to simulate & compare two waveMaker (Piston vs Flap Wavemaker) and My first requirement is " Piston Wavemaker CEL expressions "
I'm attempting to generate a simple linear wave in a 2D tank of length 20m and depth 5.1m. My mean water depth is 4m and my max wall displacement is 0.7m . (I've attached drawing of my setup)
The wave frequency is 0.5 Hz and the wave length is 3m.
I am new to this type of work and am a little Concerned about using Best CEL expressions
Does anyone have an example of this *.CCL File ?
I can not find “A series of expressions” for this work (Piston Wavemaker) !!!

Thanking you in advance

Define these CEL expressions:
MaxWallDisplacement = 0.7[m]
WallFrequency = 0.5[Hz]

And put this as the piston mesh motion displacement:

Wall Displacement X = MaxWallDisplacement * sin(t*WallFrequency/(2*pi))

Thank you for your response
I also have another question

Is my BCs correct?

Looks good to me.
