Seakeeping Software

[yannis_v]

Hello Everyone!
Could someone suggest open source software in order to perform sea keeping calculations? It will be used academically so it is better that commercial software is not used. I've used ANSYS AQWA and Maxsurf Motions before. It will be used to calculate ship structures, and not Platforms, so strip theory capabilities are welcomed!

Thank you all

NEMOH, developed by Ecole Centrale de Nantes researchers. You have just to register, before download the source. And there is a Forum to help you and answer your questions.

Thank you both for your proposals. NEMOH was my go to option but unfortunately it does not support forward speed when calculating vessels. Do you have in mind any software that can support forward speed, wave spectra and that uses 3D panel method (BEM)? I know SWAN was a very capable program that integrated all the above but as far as I know it is now discontinued.

No non commercial seakeeping software in mind with the forward speed capability.
In case you can get or negotiate a license with restriction to academical usage :
>>> Hydrostar , by Bureau Veritas, can deal with a forward speed.
