Hi, This page can help you

http://abaqus-users.1086179.n5.nabble.com/

i will suggest u try and make use of Ocarflex for floating structure

Thanks for your answers. But mister Green, orcaflex can generate the loads and boundary conditions ? if yes , do you have any tutorial? 

i know is good for offshore structures and Abacus is better for the boundary conditions & load but i recommend u download the trial version n play with it as part of ur research work

Thank you!! i've got both orcaflex and abaqus i will play with both of them :p 

Uses Ansys, easily integrates Abaqus with other computational fluid dynamics software

Thanks but i guess ill use the Aqua modulus of abaqus.
