Equation for Obtaining Phase Angle Values in Ansys AQWA Hydrodynamic Diffraction

      hello, I'm simulating the response of ship motion in Ansys Aqwa HD,

      I need the empirical formula used by the Ansys program to calculate the Phase Angle value for translational and rotational motion. Is there a journal or formula equation that I can prove the calculation is the same as the Ansys calculation? i can't find it in ansys theory manual :(

      Thank You

      The RAOs are the complex values, as shown in the Aqwa Theory Manual,

      the phases of these complex values are the phase angles (in degrees) of the translational and rotational RAOs
