Hybrid Fidelity Performance Prediction

Our Multi-Fidelity tool allows us to “correct” the low fidelity models with few high-fidelity data, enabling us to achieve high-fidelity precisions at a much lower computational effort.

Surrogate Modelings

By using the state of the art tecniques we can produce fast and precise models to represent a system behaviour

Design Optimization

The latest optimization and parametrization algorithms allow for quick and advanced 2D and 3D shape optimization at the target condition

6DoF V&CPP  

The V&CPP (Velocity And Consumption Prediction Program) developed in America's Cup , flexible and scriptable optimization environment for modelling the steady-state of physical systems.It is designed primarily for the performance prediction and optimization of sailing vessels, in which hydrodynamic and aerodynamic forces are represented by surface fits to experimental or computationally generated data of each component.

Ships fitted with wind propulsion systems are subject to loads unusual for regular ships : the forces and resulting moments exerted by the wind propulsion system on the ship structure. Those loads force an atypical sailing attitude, with higher than usual angles of leeway, trim and heel. The correct resulting sailing attitude must be predicted precisely to accurately assess the global performance.

A 6DoF VPP allows for adjustments in the DESIGN (wind propulsion system dimensioning and positioning, loads and eights configuration, hull and appendages design etc..) without the need for extensive computations in order to adapt the underlying models. Our 6DoF VPP relies on fully captive CFD data , which are quicker to compute and more accurate than2DoF data needed for classic 4DoF VPPs). Moreover, they allow for more freedom on weight and CG estimates which gives more scope for design. 2DoF CFD needs to be run at fixed target displacement and trim, which limits its validity in case those are not constant.

Performance Prediction  
For sailing ships, the objective is to find the sailing condition that allows for minimum fuel consumption for a target cruising speed. The analysis result is a complete polar of the ship, expressing its behaviour at different wind conditions

Design
Airfoil And 3D-Shape Optimization
A specific parametrization tool uses state-of-the-art optimization methods to find the most efficient section. By using direct morphing techniques on 3D CAD geometries it' s possible to test different shapes and directly optimize them based on design constraints.
$303D Morphing
CFD
HydroCFD and AeroCFD
They are the specific environments based on RANS method developed to run high fidelity simulations for marine industry. For RANS simulation different tools are in production; the choice between the right tool to use is based on the project topic and its complexity.
