Non-linear motio of large amplitude floating bodie
 

Dear members,

I would like to analyse Non-linear motion of Floating circular cylinders of large amplitudes. The cylinder may be of 30m high with 10m dia with 8m wave excursions inside the cylinder. It is like a Oscillating Water Column(OWC. Any details on software for non-linear analysis,

non-linear models welcome

thanks in advance
