Nordex Selects VISTAGY’s FiberSIM Software to Develop Composite Wind Turbine Blades

WALTHAM, Mass., (USA), May 25, 2011 — VISTAGY, Inc., a leading provider of industry-specific engineering software and services, today announced that Nordex (Xetra Stock Exchange: NDX1), one of the world’s premier manufacturers of high-efficiency wind turbines for onshore use, has purchased FiberSIM^® software to streamline its entire design-to-manufacturing process for composite wind turbine blades. Nordex is using FiberSIM to develop detailed ply designs, accurate flat patterns and manufacturing output, and complete documentation for the engineering release.

FiberSIM will enable Nordex to enhance the automation of its product development process and optimize assembly glue gaps. Nordex also notes that FiberSIM is a “powerful tool” for composite design and manufacturing when used within its Creo Elements/Pro (previously Pro/ENGINEER) CAD system. FiberSIM is fully integrated into the PTC Creo Elements/Pro, Dassault Systèmes CATIA, and Siemens NX CAD systems.

“Transferring data between design and analysis can be extremely time-consuming,” said Hendrik Klein, chief designer in the Nordex Rotor Blade Division. “But during the testing phase we recognized that if we had a design tool that had a seamless interface to our CAE analysis tools, it would enable us to significantly reduce the product development cycle.

“FiberSIM also enhances the automation of our development processes, helps us improve blade quality, and alleviates time-consuming reworks in the factory.”

“We’re very pleased that Nordex, one of the premier names in wind energy, has recognized the value of FiberSIM,” said Dr. Olivier Guillermin, director of product & market strategy for VISTAGY. “As the wind industry moves toward bigger and more complex blade designs, we’re seeing a maturation of the wind blade engineering process worldwide, and VISTAGY’s products and services are playing a key role in that development.”
