    I need help regarding the Air Gap of Semi Submersible Structure in Ansys AQWA. In Pressure and Motions of Air Gap in Hydrodynamic Diffraction Analysis, The height of the semi submersible is 36 m and draft operational is 20.5m.

    It says maximum value is 22m and minimum value is -27m, and the animation shows that the wave will not hit the bottom of the deck at all and has a half distance of air between wave and the deck.

    I can't understand the maximum and minimum value and what is the datum where they were measured from.
