Generative Part Structural Analysis 1 (GP1) allows designers to understand how their designs behave and to accurately calculate the displacements and stresses within the part under a variety of loading conditions. Analyses can be performed on volume parts, surface parts, and wireframe geometries.
GP1 is intended for designers who are not experts in finite element analysis. The analysis specification is an extension of the design specification and the analysis is performed directly on the design geometry. The user interface is a natural extension of that in the CATIA design workbenches. This makes it intuitive and natural for designers to use GP1 to ensure that their parts meet their design requirements.
- Allows designers to more accurately size parts and understand the mechanical behavior of their designs.
- Provides rapid and accurate assessment of stress and displacement characteristics.
- Analysis is performed within the CAD environment so the analysis model is fully associative with the CAD geometry and specification.
- Seamless analysis data management within PLM.

No boundary between design and analysis
GP1 is an easy-to-use tool tailored to designers and design engineers. The native integration within CATIA allows users to perform stress and displacement analysis at any time in the design process, allowing more accurate sizing of parts and fewer design iterations. Individual parts consisting of solid, surface, and wireframe geometries can be analyzed under a variety of loading conditions. The analysis specifications, such as loads and restraints, are associative with the design, allowing users to perform analyses quickly and easily.
Straightforward analysis definition
The analysis specifications, including loads, restraints, and material characteristics, are applied directly to the design features. These specifications are then automatically incorporated into the underlying finite element model, meaning that users do not have to work directly with the finite element model.
Interactive interpretation of results
GP1 provides a number of ways for a designer to understand the behavior of their design. The deformed shape can be plotted and the displacements scaled to ensure that they are visible. The displacements and stresses can be visualized using contour plots, which can be displayed on either the undeformed or the deformed shape of the part. A cutting plane can be dynamically moved though a part, with contours shown on the cut plane, allowing the behavior of complex parts to be studied interactively. Any of the principal stresses or the von Mises stress can be plotted. The von Mises stress is particularly useful to determine if the loading would cause yielding of the material and permanent deformation of the part.
Standard reports can be automatically generated in HTML format, providing clear and detailed information about the results of the analysis, including images associated with the computations. These reports can be used to document the analyses that have been performed and to communicate the results of the analysis to other stakeholders in the organization.
GP1 allows the user to control the size of the mesh on the entire part or in specific areas, switch between linear or quadratic elements, and create, modify, and remove elements directly.
GP1 uses a state-of-the-art sparse solver that computes the results rapidly while minimizing the amount of memory consumed. It takes full advantage of the additional memory available in 64 bit computers and will run in parallel on multi-core computers allowing the solution of very large models.
The knowledge associated with design analyses can be captured and used to perform optimization. The generative analysis specifications are recognized as knowledge parameters called “sensors”, providing measures that can be re-used. Rules, checks, and formulae can be used to define best practices and ensure that analyses performed are compliant with corporate standards.
The user can manage both the external storage and the location where the temporary data are stored.
