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.

hi,

i can advise you to check multisurf, which is a very capable parameteric surface modeller for ship hulls. but there are also more good alternatives.

for hull form transformation you can check this link as well;

i hope this helps.

Thank you very much. Have you ever used Multisurf for ship CFD?

regards!

hi boris,

my experience with multisurf + cfd is limited on some testing runs as multisurf -> iges to mesher -> cfd. but at least i know a guy who is using multisurf via frienship system to shipflow for automatic hull form tranformation and optimization successfuly. you can find good related papers in frinedship system web site... there was also a paper for parametric submarine cfd design automization with multisurf at somewhere in aerohydro's web site.

best regards,
