VISTAGY Inc. (Waltham, Mass.) has introduced FiberSIM 2010, the latest version of its engineering software for designing and manufacturing composite structures. The new version includes a number of improvements: A new rules-driven, structure-based design capability enables users to capture the design intent and corporate standards to ensure the production of optimized and manufacturable composite structures. A volume-fill composite ply development capability — designed specifically for wind turbine blades and other thick laminates — automates the creation of ply shapes to fill the area between the upper and lower laminate surfaces, which dictates the part shape. The software also performs multilayer material simulation to model the drapability of noncrimp fabrics and the corresponding manufacturing processes, such as forming. An improved connection between design and analysis enables more efficient transfer of composite design requirements, including new finite element analysis (FEA) interfaces with ANSYS Composite PrepPost, MSC Patran, NX Laminate Composites, BETA CAE Systems ANSA and a generic BDF data format that maps all laminate properties to the mesh. Other new features include a standardized 3-D, model-based representation of the composite part definition and functions that compare the as-built part to the as-designed and analyzed part, ensuring adherence to design specifications.
