About The Customer
Cleveland Golf, based in Huntington Beach, Calif., is a market-leading golf club manufacturer and a pioneer in the design and production of advanced clubs. The company is the developer of the number-one wedge in the golf industry. Cleveland Golf's engineering research team uses simulation to virtually assess and tune the performance of forward-looking designs to develop market-leading woods, irons, wedges, and putters. The company operates in a difficult regulatory and business environment, with the United States Golf Association (USGA) imposing limitations on golf club heads and consumers not buying as many clubs as they did in the past.
The Challenge
Cleveland Golf, a leading golf club manufacturer, faced the challenge of meeting changing regulations for golf club design while consistently introducing new products that are precisely engineered for shape, feel, balance, sound, and performance. The United States Golf Association (USGA) imposes limitations on golf club heads, including the size of the grooves in wedges and irons, the dimensions of the head, and the permitted coefficient of restitution (COR) – or springiness – that is allowed in clubs. As clubs have improved, they've reached these limits and have the capability to go beyond them. This posed a significant challenge as Cleveland Golf needed to figure out how to continue to improve clubs without exceeding these limits. Additionally, the USGA recently changed the rules specifying groove size, impacting how future clubs will be designed. From an economic standpoint, consumers were not buying as many clubs as they did in the past, so Cleveland Golf needed to create more new and innovative products, not just variations on existing clubs.
The Solution
Cleveland Golf employed the HyperWorks suite of software for CAE design simulation to address these challenges. The research team used this software to balance a variety of design variables, including materials, size, shape, weight placement, thickness patterns, and placement of internal ribs for durability, sound, and feel. They also used HyperStudy to optimize material properties, along with AcuSolve® to explore the club’s aerodynamics. In addition to evaluating the structural performance of prototypes, Cleveland Golf used simulation to predict the sound that the club head makes when striking the ball, employing modal analysis using the HyperWorks OptiStruct® solver. They compared new club designs with previous parts in running their sound analyses and used a robot that strikes golf balls consistently, enabling the engineers to test different design iterations and to measure the sound coming from the club. Player testing was also used for feedback on sound and feel and to compare Cleveland Golf clubs with others in the market.

Revolutionizing Medical Training in India: GSL Smart Lab and the LAP Mentor
The GSL SMART Lab, a collective effort of the GSL College of Medicine and the GSL College of Nursing and Health Science, was facing a challenge in providing superior training to healthcare professionals. As clinical medicine was becoming more focused on patient safety and quality of care, the need for medical simulation to bridge the educational gap between the classroom and the clinical environment was becoming increasingly apparent. Dr. Sandeep Ganni, the director of the GSL SMART Lab, envisioned a world-class surgical and medical training center where physicians and healthcare professionals could learn skills through simulation training. He was looking for different simulators for different specialties to provide both basic and advanced simulation training. For laparoscopic surgery, he was interested in a high fidelity simulator that could provide basic surgical and suturing skills training for international accreditation as well as specific hands-on training in complex laparoscopic procedures for practicing physicians in India.
