New Version of FiberSIM/UG

01 November 2000

Composite Design Technologies, Inc. announced the release of Version 3.3 of FiberSIM/UG software for composite design and manufacturing on the Unigraphics CAD system from Unigraphics Solutions. The new version includes a number of significant enhancements that provide companies using Unigraphics to design composite components with the opportunity to substantially increase engineering productivity. "Version 3.3 enhances previous FiberSIM capability, allowing engineers to accomplish more in less time," said John O'Connor, CDT Technical Consultant, FiberSIM/UG Product Line. "Users will discover a wide range of improvements that simplify and streamline the operation of the program, making it possible to focus their attention more fully on the design process." One major improvement enables users to import stored ply definitions into the FiberSIM Composite Engineering Environment, including material name, fiber spacing factor, simulation type as well as additional geometric data such as holes and markers. This feature saves time by eliminating the need to re-enter information when opening a previously created Unigraphics model. FiberSIM/UG 3.3 also provides the ability to accurately simulate complex curvature parts using liquid composite molding manufacturing techniques through a link to LCMFLOT, mold filling analysis software from Liquid Process Performance Prediction, Inc. (L3P). This makes it possible for companies investigating this fast growing composite manufacturing method to more accurately simulate the flow of resin through a mold without the expense and ime involved in building and testing a prototype mold. Additional enhancements in the data interface area include the ability to export flat patterns in the popular DXF file format and to generate laser projection data far more quickly than in the previous version.n FiberSIM/UG 3.3 is now available on HP (HP-UX), SGI (IRIX), and Windows NT. Additional platforms will be supported in the future. FiberSIM is a suite of software products that transforms CATIA, Pro/ENGINEER and Unigraphics CAD systems into high performance environments for designing and manufacturing composite parts. The FiberSIM product suite includes tools that automate the design process, assess the producibility of a part, and generate manufacturing information including documentation, flat patterns, and data to interface with laser projectors, automated cutters and fiber placement machines. Consequently, FiberSIM enables users to drive all aspects of preliminary design, analysis, detailed design, and manufacturing from within a single CAD master model.
