30 degrees roll? Your GZ curve will be non linear. At your smaller angles (the last few oscillations) it is starting to stabilise...
Look up "Standardized Wave and Wind Environments for NATO Operational Environments" by Susan Bales et al. It contains a scatter table of the type...
Or just use Rhino to develop the shape using only "developable surfaces", then analyse stability in a different package. Rhino will allow you to...
To include free surface effects the CFD code has to solve in the time domain, as surface waves move. So it needs Iyy to solve the equations of...
You could start by looking at the ITTC procedures: http://ittc.info/media/1575/75-02-02-01.pdf http://ittc.info/media/1593/75-02-03-014.pdf
