    Hi,

    As I understand, the hydrodynamic database (RAOs, forces, damping, etc) aqwa creates is about the centre of gravity. According to the manual (25.7. The REFP Data Record - New Hydrodynamic Reference Point https://www.sharcnet.ca/Software/Ansys/15.0.7/en-us/help/aqwa_ref/aqwaref_deck16L_refp.html), I should be able to define a new reference point (which I would like to be the SWL). I'm able to change this in data category 16 and I'm inclined to believe that my formatting is correct since aqwa runs without errors and the output .lis file suggests that the hydrodynamic reference point is read correctly (see attached images). However, the new outputs provided after the shift are the exact same as those prior regardless of the point I change to (even when I input extremely high values).

    I'm at a bit of a loss here and would greatly appreciate anyone who could point me in the right direction as to why the outputs do not change/what I'm doing incorrectly.
