We are trying to use CFD simulations as an approach to modify hull forms in order to achieve better ship hydrodynamic performances.

However, at the moment, we don't have good CAD tools. Each time, we use ship offsets to create the model geometry and do the modeling. After the simulations, we may find out some parts of the hull from that can be modified. Then, we can't change the hull form in a easy way, as we don't have an appropriate CAD tool to change the hull form and to do the faring as well.

Please kindly provide the info of what CAD tools nomarlly used for ship CFD.

Thanks in advance.

Have a look at www.think3.com They have a feature called "global shape modelling" which might be what you are looking for.
