America’s Cup teams leverage Cadence CFD solutions to optimize hydrodynamic performance
Cadence Design Systems, Inc. has announced that three teams participating in the 37th America’s Cup will rely on Cadence’s Computational Fluid Dynamics (CFD) solutions to help improve their overall racing performance: Emirates Team New Zealand , four-time winner and defending champion, Challenger of Record INEOS Britannia and New York Yacht Club American Magic. The America’s Cup is sailing’s flagship race and offers incredibly competitive and thrilling races for sailing enthusiasts around the world. The next highly anticipated edition will take place in 2024.
Hydrofoil technology had a sensational impact on the 2013 America’s Cup race, exemplified by an exciting race between Emirates Team New Zealand and Oracle Team USA. Hydrofoils are wing-like structures attached under the hull of a racing boat that lift the boat out of the water at increased speeds, making it appear to be flying above the surface. Emirates Team New Zealand has used Cadence’s Fidelity™ Marine technology in their hull and hydrofoil design since racing in 2013. In 2021 they lifted the coveted Auld Mug trophy for the fourth time, the oldest in international sports .
The hydrofoil and efficiency in the water are essential when every second counts in highly competitive racing. With increasing demands for efficiency, fidelity and speed in the water, Cadence CFD solutions offer multidisciplinary technologies that enable design teams to analyze and model real-world scenarios, enabling them to determine designs optimal for maximum performance, long before the first prototype hit the water.
“The AC75 yachts used in the race actually spend most of their time flying above water,” said Dan Bernasconi, technical director of Emirates Team New Zealand. “By having a hull design optimized for hydrodynamic efficiency from take-off and touchdown, we are much better equipped to predict performance. Cadence Fidelity Marine is the leader in hydrodynamic modeling and simulation and is an important part of from our full suite of tools.
INEOS Britannia, competing in their third consecutive America’s Cup campaign, have a strong squad for the event. The team plan to learn from the experience of their previous two campaigns to lead a difficult charge to bring the America’s Cup to Britain for the first time in their history.
“Simulation and CFD are the main tools used to predict and fine-tune the performance of our America’s Cup racing boat,” said INEOS Britannia chief designer Martin Fischer. “In terms of selecting a provider for these services for the AC37, we at INEOS Britannia believe that Cadence Fidelity solutions will best meet our needs.
The New York Yacht Club American Magic, formed in 2017, is heading towards a vision to “reclaim” the cup. The team’s name includes a nod to the New York Yacht Club’s 101-foot schooner “America” which won the first race in 1851, as well as “Magic”, the first yacht to defend successfully the Cup in 1870. In this first race, “America” finished eight minutes ahead of its nearest rival and thus obtained the namesake of the race.
“American Magic has selected Cadence Fidelity Marine software as its primary CFD tool for hydrodynamic analysis and design because it continues to provide industry-leading numerical simulation capabilities for marine applications,” said Len Imas, PhD, of the American Magic design team. . “Among commercial and research codes in use today, it has remained the industry leader over multiple America’s Cup campaigns by providing robust and accurate results and expanding functionality in areas involving the analysis of high performance hull and appendage design, marine vehicle dynamics and fluid structural interactions.
