1 FINE TM /Marine CFD Suite for Marine Applications Advanced Development for Better Products

2 FINE TM /Marine FINE /Marine is a unique integrated CFD software environment for the simulation of mono-fluid and multi-fluid flows around any kind of ships, boats or yachts including various types of appendages. The powerful and customized graphical user interface drives the user into the whole simulation FINE TM /Marine process and integrates : marine-dedicated features for different applications. the leading CFD package for naval architects Computational Fluid Dynamics (CFD) offers the capability to bring innovative, efficient solutions into the design process of the marine industry. In comparison to experimental testing facilities, CFD offers clear technical advantages including full-scale modeling and in-depth analysis of flow phenomena. Furthermore, overall project costs and turnaround times can be significantly decreased when a CFD analysis is incorporated into the design cycle. State-of-the-art RANS CFD approaches predict the flow not only qualitatively ( delta-s ), but also on a quantitative level (for both low and high Froude number flows). And as computer hardware costs continue to decrease, CFD analysis is now an economically attractive option for numerous marine applications including resistance & propulsion analysis, seakeeping, manoeuvring, optimization studies, and hydraulics. Rather than using CFD as a verification tool alone, close integration of CFD as early as possible in the design loop is bringing large added value to the engineering process. This approach provides a relatively cheap but reliable tool to identify the best candidate models, even at the concept phase, leading to more efficient designs at reduced costs and thus minimizing costly design changes at later project stages. To provide an optimal CFD solution to these marine specific problems, NUMECA has released FINE / Marine, considered the leading CFD package for naval architects. Services NUMECA has a team of highly qualified engineers providing a wide variety of services to the marine industry, ensuring that your organization makes use of our tools in the best and most efficient way. We offer : Consulting Adaptation and customization of FINE TM /Marine towards user s specific requests Integration of NUMECA suite into the customer s CFD workflow Development of interfaces towards in-house CFD tools

4 SAILING YACHTS After considering various free-surface capturing CFD tools for hydrodynamic analysis applications involving high performance racing yachts, Emirates Team New Zealand (ETNZ) has selected NUMECA s FINE /Marine as the unique Navier- Stokes based simulation suite to serve in that capacity during ETNZ s 34th America s Cup design campaign. We believe that in comparison to alternatives, FINE /Marine produces consistently higher fidelity solutions across a very broad range of sailing conditions thereby making it the analysis tool of choice. Dr. Len Imas, Emirates Team New Zealand Resistance calculation including hydrofoils Thanks to its powerful scripting capabilities and accuracy, we have been using FINE /Marine extensively to effectively optimize yacht and ship hull designs in a fully automatic manner. [ ] We were able to achieve three times the hull drag reduction of a competitor who used a standard panel code connected to common parametric optimization system." Jason Ker, Ker Design Sailing yacht in headwind Despite a limited research and design time frame we have incorporated a number of innovative appendage features into the design. We utilized NUMECA s FINE /Marine RANS flow solver and the FYD high performance computing cluster to study some of the hydrodynamic trade-offs associated with these features.

5 OFFSHORE VESSELS AND CRUISE SHIPS OFFSHORE VESSELS & CRUISE SHIPS The recent key decision of NUMECA International to enable the user to script the FINE /Marine stage of the CFD process has changed our way to work. In addition, choosing python as default language makes it easier for a naval architect to start programming. As a consequence, a few days were sufficient to acquire the basic knowledge needed to start building scripts. We are now in a situation where we have scripts for different types of applications: resistance curves are made within a minimum of human time!
