Development of interfaces towards in-house CFD tools

Computational Fluid Dynamics (CFD) offers thecapability to bring innovative, efficient solutions into thedesign processof the marine industry. In comparison to

experimental testing facilities, CFD offers clear technicaladvantages including full-scale modelingand in-depthanalysis of flow phenomena. Furthermore, overall projectcosts and turnaround times can be significantlydecreasedwhen a CFD analysis is incorporated into thedesign cycle.State-of-the-art RANS CFD approaches predict the flow notonly qualitatively(delta-s), but also on a quantitativelevel (for both low and high Froude number flows).And as computer hardware costs continue to decrease,CFD analysis is now an economically attractive optionfor numerous marine applications including resistance& propulsion analysis, seakeeping, manoeuvring,optimization studies, and hydraulics.

Rather than using CFD as a verification tool alone, closeintegration of CFD as early as possible in the designloop is bringing large added valueto the engineering

process. This approach provides a relatively cheap butreliable tool to identify the best candidate models, evenat the concept phase, leading to more efficient designsat reduced costs and thus minimizing costly designchanges at later project stages.

To provide an optimal CFD solution to these marinespecific problems, NUMECA has released FINE/Marine, considered the leading CFD package for navalarchitects.

FINETM/Marine

FINE/Marine is a unique integrated CFD software environment for the simulation ofmono-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 process and integrates marine-dedicated fea-tures for different applications.

Thanks to its powerful scripting capabilities and accuracy,we have been using FINE/Marine extensively to effectivelyoptimize yacht and ship hull designs in a fully automatic man-ner. [] We were able to achieve three times the hull dragreduction of a competitor who used a standard panel code con-nected to common parametric optimization system."

SAILING YACHTS

After consider ing vari-ous free-surface capturingCFD tools for hydrody-namic analysis applica-tions involving high per-formance racing yachts,Emirat es Team NewZealand (ETNZ) hasselected NUMECAsFINE/Marine asthe unique Navier-Stokes based simu-lation suite toserve in that capac-

parison to alternatives ,FINE/Marine pro-duces consistently higher

fide li ty solutions across avery broad range of sail-ing conditions therebymaking it the analysistool of choice.

Despite a limited research and design time frame we have incorporated anumber of innovative appendage features into the design.

We utilized NUMECAs FINE/Marine RANS flow solver and theFYD high performance computing cluster to study some of the hydrodynamictrade-offs associated with these features.

OFFSHORE VESSELS & CRUISE SHIPS

The recent key decision ofNUMECA Internationalto enable the user to script

t h e F INE/Mar inestage of the CFD processhas changed our way towork. In addition, choos-ing python as default lan-guage makes it easier for anaval architect to startprogramming. As a conse-quence, a few days weresufficient to acquire the

basic knowledge needed tostart building scripts. Weare now in a situation

where we have scripts fordifferent types of applica-tions: resistance curves aremade within a minimumof human time!
