UGS and FunctionBay Announce Partnership to Extend Breadth of NX Digital Simulation Software through Open Simulation Framework


Agreement Enables Advanced Simulation Capabilities in the Areas of Large-Scale, Multi-Body Motion Analysis

DARATECH SUMMIT 2006, CAMBRIDGE, Mass. – UGS Corp., a leading global provider of product lifecycle management (PLM) software and services, today announced that UGS and FunctionBay, Inc. have entered into a technology partnership that enables UGS to leverage the RecurDyn™ multi-body dynamics solver in NX™ Digital Simulation software.

UGS made this announcement in conjunction with its Lifecycle Simulation announcements at today’s opening of the Daratech Summit 2006 event in Cambridge, Mass., where UGS Chairman, CEO and President Tony Affuso delivered a keynote address. (see separate release)

“The UGS PLM Open business model provides an enabling architecture that allows our partners to easily integrate their solutions with our products,” said Affuso. “The partnership with FunctionBay supports our Lifecycle Simulation strategy, featuring the world’s first end-to-end Digital Simulation solution UGS is keenly focused on elevating the role of CAE within the digital product development process. The goal is to provide our customers a comprehensive range of CAE applications – including UGS and partner solutions – to help them achieve product innovation"

RecurDyn™/Professional is an advanced multi-body dynamics software that is founded on a recursive formulation for the equations of motion, relative coordinates, and advanced numerical integration techniques. The solution simulates simple through complex mechanical systems that are made up of rigid or flexible bodies.

“We are very pleased to partner with UGS to accelerate RecurDyn technology into the global digital simulation industry through NX Digital Simulation,” said Jin H. Choi, chairman, FunctionBay, Inc. “UGS’ open simulation framework has provided us an efficient integration process, and we look forward to working with UGS to further extend our offering within the NX environment.”

“UGS is excited to expand its simulation capabilities to include a new, multi-body dynamics solver,” said Jim Rusk, vice president, UGS Digital Simulation Solutions. “Partnering with FunctionBay provides our customers flexible options to select the motion simulation technology that best meets their specific application requirements. RecurDyn has demonstrated excellent performance and is well-known in the industry.”

How RecurDyn Works

RecurDyn uses a unique calculation method to solve for dynamic behavior and provides notable advantages for all engineers, but especially those who require tight design and analysis activity integration, motion simulation best practice templates and motion simulation data management.

Typical industrial applications include:

§ High-Tech/Consumer electronics – copiers, printers, disk drives, home appliances, camera mechanisms, DVDs, etc.

§ Automotive/Vehicle – engine assemblies/sub-systems, transmission/drivetrain assemblies and sub-systems, door mechanisms, wiper mechanisms, etc.

§ Heavy Equipment – crawler tractors, tracked construction equipment, farm equipment, cranes, excavators, etc.

§ Aerospace/Defense – aircraft landing gear systems, hydraulic actuation systems, guidance systems, satellite systems, land-based rovers, aircraft engines, etc.

The new RecurDyn capabilities will be available next quarter in the maintenance release of NX. Future releases of NX will incorporate additional advanced RecurDyn features.
