This is another parameter from physics and describes the distance between the highest and the lowest point of an oscillation. Some books define it as the distance between the highest or lowest point and the wave’s baseline. In connection with the “Control Points” modifier, “Amplitude” is the maximum elongation (or "height") of the points given in metres [m].
Begin time
You will be able to exactly define the time in seconds when [s] when the points should start oscillating. This is especially useful with more than one "Control Point" modifier. You could start with wave generation at different times and create interesting interactions.

The waves will have some initial speed once they are created. Wave speed is the other measure for the wave’s energy. With activated damping, higher and faster waves will travel longer and not vanish so fast. In RealFlow, speed is measured in metres per second [m/s].
Damping
Without damping a wave would travel for ever, regardless from the initial amount of energy. Under real conditions, water waves will always lose their energy. This results in waves, becoming flat and slower over time until they completely vanish. “Damping” controls how fast the waves disappear. With strong or undamped waves, they become reflected at the RealWave mesh’s borders, creating more structures and ripples. For a realistic appearance, waves should always have at least a small amount of “Damping”.
