Improving enterprise collaboration

Paul Boughton

Integrated within the Catia V5 Product Lifecycle Management (PLM) solution from Dassault Systèmes, the latest software product from the SIMULIA brand improves the deployment of high-value analysis workflows and advanced simulation technology across product development organisations in a wide range of industries, including ground vehicles, aerospace and defense, biomedical, and others.

Version 2.3 of Abaqus for Catia V5 takes advantage of the latest technology advances in Abaqus Version 6.6 and Catia V5 R16 to deepen its capabilities, with particular emphasis on new enhancements in contact modeling, connections, and usability.

The tight integration of Abaqus with Catia enables advanced methods developed and validated by Abaqus specialists to be deployed to the enterprise as proven analysis workflows. The software enables both design engineers and analysis specialists to use the same FEA methods and models within Catia V5, ensuring repeatability and accuracy.

The latest product release builds on the Simulia strategy of providing scalable simulation solutions and an open framework for performing multidisciplinary analysis within the PLM process.

Improvements to Version 2.3 of Abaqus for Catia V5 focus on providing immediate benefits in production environments. New capabilities in the software include:

* Support of Version 6.6. Takes advantage of complete functionality of Abaqus/Standard solver capabilities, including contact enhancements and performance improvements.

* Spot, seam, and surface weld modeling. Leverages the weld modeling functionality of Catia V5 to enable rapid definition of a large number of rigid or flexible connections. New capabilities and improvements account for spot, seam, and surface welds. Connection locations can be independent of the underlying mesh, which reduces model size and complexity of the meshing requirements. Combined with Abaqus contact capabilities and the ability to simulate large deformation, the new weld features make Abaqus for Catia V5 an attractive analysis tool for airframe and automotive body modeling.

* Abaqus continuum shell technology. Enables the modeling of shell structures with continuum shell elements, which permits the use of the actual CAD geometry of the structure rather than determining an approximate midplane and appropriate offsets of adjoining components. This approach simplifies modeling and improves accuracy of simulations involving contact.

* Contact enhancements. Takes advantage of Abaqus Version 6.6 contact capabilities, including the ability to model applications involving large sliding between parts, using the surface-to-surface formulation. Usability enhancements include the ability to view some or all of the parts in a complex contact analysis, which can assist in confirming the selection of contact surfaces.
