CATIA for Engineers enables Digital Prototyping including Analysis and Simulation for design and validation of function quality and performance at all stages ofthe design.
Mechanical engineering is complex as assemblies are designed to perform a specific task with a specific target performance. Digital prototyping, combined with digital analysis and simulation, allows product development teams to virtually create and analyze a mechanical product in its environment. Mechanical engineers must be equipped with these tools so that they can gain insight into key factors in quality and performance early in the product development phase.
CATIA Composites Engineering
Productive process-oriented environment dedicated to the design of composite parts from preliminary to engineering detailed design.
Composite materials offer a new world of design possibilities along with high-performance products. In order to capitalize on these possibilities, designers need dedicated and powerful composite tools that allow composite designers and manufacturing teams to enjoy trouble-free collaboration.
The collaborative and integrated CATIA Composites Engineering environment fosters the rapid creation of innovative composite parts for the aerospace, automotive, wind energy, and shipbuilding industries. Designers can work concurrently on the same design, while composites manufacturing constraints can be embedded early in the conceptual stage, dramatically shortening design time.
In addition to the zones and tapers approach, two new approaches, grid design and solid slicing, have been developed for a variety of industries. The design of aerospace barrels, boat hulls, and wind turbine blades can particularly benefit from the grid design approach to mate better with structural parts. The solid slicing approach is especially beneficial to optimize composite design steps for aerospace engine turbine blades, energy structural elements, and reengineering of metal parts.

Grid based design in assembly contextThe design of large composites parts, for example aerospace barrels, wings, turbine blades, or boat hulls, may be processed in an assembly context with mating structural elements. These mechanical interfaces, such as stiffeners, stringers or frames, are taken into account through their footprints displayed on a grid panel. The ply stacking can be controlled in a virtual representation by the management of cells and ply order. The plies are then generated from the grid with automatic management for stacking and staggering.
Easy-to-use zones and modeling definition of transition zonesDuring conceptual design, zones and groups of zones are defined, including geometry and laminate. Knowledgeware parameters are automatically created to automate the geometry update in case of design changes. Transition zones define the area of the ply drop-off between two zones.
Powerful ply generation from grid, zones and taper or from zones and solid slicingDepending on the part category, the user may choose between these three modeling approaches. First, for large and structured parts, the grid design presents a virtual stacking definition and grid panel staggering constraints. Second, the zone and taper approach is particularly suitable for core-stiffened parts, where core inserts such as honeycomb can be created inside the composites structure. In addition, a new approach of plies creation from solid slicing is fitted for thick monolithic parts (engine turbine blades, for instance) or for re-engineering of metal parts. This makes it possible to slice the conceptual solid resulting from the zones and to generate the plies directly from the slicing curves, so that they are associative with every previous definition feature.
Mighty ply modeling tools based on 3D featuresPowerful modification features allow users to optimize ply shapes and drop-offs. The geometry, material, direction or rosette of a ply can be modified manually, or core inserts - such as honeycomb - can be created inside the composites structure. Merge and symmetry are available to enhance Collaborative Design. Grid design can be modified by dedicated features: swap or reroute edges or local drop-offs management. Associative solids can be refined manually by adding plies.
Best-in-class solid generation and top surface or Inner Mold Line generation from zones and pliesAt the end of the conceptual design, an associative exact solid can be created for 3D mock up integration, space allocation, interferences checking, definition of the footprint surface of substructural parts. Similarly, top surface or Inner Mold Line can be generated from zones and plies.
Complete composites data query toolsData query tools include core sampling, numerical analysis and ply table. Easy export of the numerical analysis offers quick comparison of ply characteristics.
Ply productibility validated with high quality tools for early manufacturability assessmentThe fiber behavior, such as deviation and deformation can be analyzed at different points of several plies. Simulation tools allow users to avoid manufacturability problems such as wrinkling and bridges of fibers.
Facilitate innovation, save time, and reduce expenses with the CATIA V6 offerHigh level of automation and standardization are brought by rules instantiated in stacking sequences to take industrial standards and corporate know-how into account. CATIA V6's preliminary design knowledgeware capabilities enable users to update a part automatically for design change purposes. This prevents the need to restart the full design phase. Composites engineering takes advantage of other applications (FEA, DMU, Machining, etc.). And automatic updates reduce the impact of changes to the design-to-manufacturing process. In addition, the CATIA V6 infrastructure offers a truly collaborative composites engineering environment that enables designers to work concurrently.
High level design of complex geometrical configurationsOwing to their geometrical configuration, some composites parts require complex designs. Composites engineering can manage multi-part geometries, such as T-shaped parts, monolithic and core stiffened parts, and stiffeners and stringers more easily than standard composites design solutions.
New ply bookIn the drafting workbench, the user can choose whether each sheet of this new ply book will be associated to a single ply/cut piece, to a sequence, or to all cut-pieces. All the views of the reference sheet are generated for each new ply in new sheets with the same view properties, position and links.
