WaveHeight not consistent with piston generation?
I am doing a simulation using a piston to generate waves unto a beach. The piston parameters are:
After the ramp periode I see that the amplitude of the pistion motion matches the given amplitude of 0.305757 m. But when I use a gauge to analyze the wave height as such (green is wave gauge):
Which is about 0.18 m above 0 (still water level). To my understanding WaveHeight = 2 * WaveAmplitude, which means in this case using gauge I find WaveHeight = 0.36 m, but in my initial piston settings it said it would only produces waves of height 0.3 m?
Can anyone clear my confusion / explain to me why my settings are not implemented properly - it is a difference of 20%..
