Using CFD to optimize hydrodynamics performance for the America’s Cup

June 6, 2022 By WTWH Editor Leave a Comment

Cadence Design Systems, Inc. announced that three teams competing in the 37th edition of the America’s Cup will be counting on Cadence computational fluid dynamics (CFD) solutions to help them improve overall race performance: four-time winner and defending champion Emirates Team New Zealand, Challenger of Record INEOS Britannia, and New York Yacht Club American Magic. The America’s Cup is the pinnacle race in sailing and offers incredibly competitive and exciting racing for sailing enthusiasts around the world. The next highly anticipated edition will be held in 2024.

Hydrofoiling technology made a sensational impact on the race in the 2013 America’s Cup, which was illustrated in an exciting race between Emirates Team New Zealand and Oracle Team USA. Hydrofoils are the wing-like structures attached under the hull of a race boat that lift the boat out of the water at increased speeds, making it appear to fly above the surface. Emirates Team New Zealand has been leveraging Cadence’s Fidelity™ Marine technology for their hull and hydrofoil design ever since the race in 2013. In 2021, they raised the coveted Auld Mug trophy, the oldest in international sports, for the fourth time.

Hydrofoiling and efficiencies in the water are critical when every second counts in highly competitive racing. With an increasing demand 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 optimal designs for maximum performance, long before the first prototype touches the water.

“The AC75 yachts used in the race actually spend most of their time flying above the water,” said Dan Bernasconi, technical director Emirates Team New Zealand. “By having a hull design optimized for hydrodynamic takeoff and touchdown efficiency, we are much more equipped to predict performance. Cadence Fidelity Marine is the leader in hydrodynamic modeling and simulation and is an important part of our comprehensive tool suite.”

INEOS Britannia, which is competing in its third consecutive America’s Cup campaign, has a strong team lined up for the event. The team plans to learn from the experience of its previous two campaigns to lead a hard charge towards bringing the America’s Cup to Britain for the first time in its history.

“Simulation and CFD are the principal tools used to predict and refine the performance of our America’s Cup race boat,” said Martin Fischer, INEOS Britannia chief designer. “When it came to selecting a provider for these services for AC37, we at INEOS Britannia believe the Cadence Fidelity solutions will best fit our needs.”

New York Yacht Club American Magic, formed in 2017, is driving towards a vision to “win back” the cup. The team name includes a nod to the New York Yacht Club’s 101-foot schooner “America” that won the first race back in 1851, as well as to “Magic,” the first yacht to successfully defend the Cup in 1870. In that first race, “America” finished eight minutes ahead of their closest rival and thus garnered the namesake for the race.

“American Magic has selected the Cadence Fidelity Marine software as its primary CFD tool for hydrodynamic analysis and design as it continues to provide state-of-the-art numerical simulation capabilities for marine applications,” said Len Imas, PhD, American Magic Design Team. “Among commercial and research codes in use today, it remains the industry leader over the course of multiple America’s Cup campaigns by providing robust and accurate results and expanding functionality in areas involving high-performance hull and appendage design analysis, marine vehicle dynamics and fluid-structure interaction.”

With Cadence’s CFD software, McLaren can investigate optimal designs in less time

May 31, 2022 By WTWH Editor Leave a Comment

Cadence Design Systems, Inc. announced that it has become an Official Technology Partner of the McLaren Formula 1 Team. Through the multi-year partnership, McLaren has access to Cadence Fidelity CFD Software, which provides innovative aerodynamic prediction tools that can help accelerate the team’s path toward victory.

In racing, shaving off a fraction of a second per lap can make all the difference when it comes to a podium finish. McLaren will use the Cadence Fidelity CFD Software, a comprehensive suite of computational fluid dynamics (CFD) solutions, to investigate airflow. The team will also leverage Cadence’s computational software expertise to tackle design projects that require advanced compute power and precision.

“We’re delighted to welcome Cadence to the McLaren Racing family. Cadence is a technology leader that prioritizes innovation. Its CFD and advanced electronic technologies will be crucial assets for our design operations. We look forward to a fast-paced collaboration that supports our constant drive to boost our on-track performance. The Monaco Grand Prix is a fantastic event to launch our partnership, and we’re excited that Cadence will join our brand across multiple race series this weekend by running on the Arrow McLaren SP cars for the Indy 500,” said Matt Dennington, director of partnerships, McLaren Racing.

“As part of the McLaren Racing family, we’re bringing our Fidelity CFD Software to the team and supporting the team in its ongoing pursuit of boosting performance. We will collaborate with McLaren to continually push and innovate. We’re looking forward to the multi-year partnership and achieving milestones together that put the team on the road to victory,” said KT Moore, vice president, Corporate Marketing, Cadence.

Electrical-Thermal Co-Simulation for system analysis

September 18, 2019 By Leslie Langnau Leave a Comment

Cadence Design Systems, Inc. introduced Cadence Celsius Thermal Solver, an electrical-thermal co-simulation solution for the full hierarchy of electronic systems from ICs to physical enclosures. Based on a production-proven, massively parallel architecture that delivers up to 10X faster performance than legacy solutions without sacrificing accuracy, the Celsius Thermal Solver seamlessly integrates with Cadence IC, package and PCB implementation platforms. This enables new system analysis and design insights and empowers electrical design teams to detect and mitigate thermal issues early in the design process—reducing electronic system development iterations.

As the electronics industry moves toward smaller, faster, smarter and more complex products with greater power density, time-consuming thermal transient analysis techniques must be deployed together with traditional steady-state analysis to address multiple power profiles and increased heat dissipation. Further complicating the process, traditional simulators require the electronics and enclosures being modeled to be substantially simplified, resulting in reduced accuracy.

The Celsius Thermal Solver uses multi-physics technology to address these challenges. By combining finite element analysis (FEA) for solid structures with computational fluid dynamics (CFD) for fluids, the Celsius Thermal Solver provides system analysis in one tool. When using the Celsius Thermal Solver in conjunction with the Clarity 3D Solver, Voltus IC Power Integrity and Sigrity technology for PCB and IC packaging, engineering teams can combine electrical and thermal analysis and simulate the flow of both electricity and heat for a more accurate system-level thermal simulation than legacy tools. In addition, the Celsius Thermal Solver performs both static (steady-state) and dynamic (transient) electrical-thermal co-simulations based on the actual flow of electrical power in advanced 3D structures, providing visibility into real-world system behavior.

By empowering electronics design teams to analyze thermal issues early and share ownership of thermal analysis, the Celsius Thermal Solver reduces design re-spins and enables new analysis and design insights not possible with legacy solutions. In addition, the Celsius Thermal Solver accurately simulates large systems with detailed granularity for any object of interest and is the first solution capable of modeling structures as small as the IC and its power distribution together with structures as large as the chassis.

The Celsius Thermal Solver supports Cadence’s Intelligent System Design strategy. It is built on matrix solver technology that is production proven in the recently announced Clarity 3D Solver and the Voltus IC Power Integrity Solution. Optimized for cloud environments, the Celsius Thermal Solver’s massively parallel architecture delivers up to 10X cycle time improvements compared to legacy solutions with high accuracy and unlimited scalability.
