We provide a new concept "tool" from CAD-like geometry to final simulation with the aim of dealing parametrized shapes managed by efficient free-form deformation techniques into an isogeometric analysis setting. This tool is totally integrated model order reduction techniques, based on POD, developed for stable incompressible viscous flows (velocity and pressure) in shapes. computational environment has been created framework project UBE Underwater Blue Efficiency optimization immersed parts motor yachts, including exhausting devices. The study benefiting several properties reduced modelling approaches such as offline-online calculations parametric design, well synergies properties. Convergence, stability consistency are verified test case then applicative results introduced.
