Descrizione The objective of this internship is to develop a software tool for parametric hydrodynamic

coefficients computation based on pre-saved structures. The user would select a geometry of certain

characteristics (shape, size, draft, etc...) and, based on the pre-saved models, the program would

give the user the hydrodynamic parameters of such geometry without needing to use a BEM

(Boundary Element Method) solver. Thus, a user could quickly get hydrodynamic coefficients for a

given structure with different characteristics, without having to know how to use BEM solvers and all

the other required programs (3D modelling platforms, etc.). The platform could have a graphic and

command line interfaces and, at the beginning, we could start with simple bodies, such as cylinders

and spheres, which are easy to parametrize given their radius and draft. After that, it would be

interesting to see if it's possible to parametrize geometrically more complex devices as combinations

of simpler structures (such as, for example, Corpower device which could be defined as a

combination of two cylinders and a truncated cone).

During a 4-months internship, the student would, first, develop different sets of hydrodynamic

models using WAMIT or NEMOH for several geometrically simple devices. Then, different

interpolation approaches to generate the final desired model, defined by the user of the software,

would be assessed. Finally, the student would develop a software where the user could select the

desired geometry and get the corresponding hydrodynamic coefficients. Finally, if more time is

available, or else for a future extension of the project, more (and more sophisticated) geometries

and interpolation methods would be added to the tool.

Note The thesis includes a period abroad (at Maynooth University in Ireland), 3 to 8 months long (length to be defined together with the candidate).
