Image 2 Abaqus_CATIA_AI.tif
The ability to explore and analyze designs rapidly is an essential requirement in many production workflows. The new CATIA V5 associative interface for Abaqus/CAE enables CAD and FEA assemblies to be synchronized for seamless update of models with geometric changes while retaining analysis attributes. This functionality allows rapid update and analysis of models such as the portable electronic device shown.

Image 3 Abaqus_Linear_dyn.tif
In this example, the frequency response of an 800,000 degree of freedom body-in-white model with material damping is examined. With the new high-performance linear dynamics capabilities in V6.7, the analysis is completed more than 300 times faster than before. With this new release, manufacturers are able to take advantage of the Abaqus Unified FEA environment for structural integrity, powertrain durability, noise and vibration behavior, crashworthiness, occupant safety, and tire-roadway interaction.

Dassault Systèmes Announces New Capability for Analyzing Fluid-Structure Interaction with Abaqus and STAR-CD
These graphics are associated with the
15-February-2007 press release.
Caption:
In this model of an engine manifold, a thermal-stress analysis is performed by coupling the computational fluid analysis results (Figure A) from STAR-CD with the structural analysis in Abaqus (Figure B). The color contour plot from Abaqus FEA (Figure C) shows temperature distribution on the manifold resulting from the flow of hot exhaust gases.

Caption:
A transient, fluid structure interaction simulation of a flexible baffle in an air stream is enabled by coupling Abaqus finite element analysis software with computational fluid dynamic (CFD) results from STAR-CD. This color contour plot of fluid pressures in STAR-CD depicts a specific instance in time, at which the polyhedral CFD mesh from STAR-CD has moved to accommodate the structural deformation of the Abaqus baffle model.

Dassault Systèmes Announces Abaqus for CATIA V5 Version 2.4
 This graphic is associated with the
11-December-2006 press release.
Caption: With Abaqus for CATIA V5 Version 2.4, engineers can simulate nonlinear load cases, such as the sag of a car door as it swings on its hinges. The car door model pictured here includes shell, beam, and solid components fastened together using a combination of spot welds, seam welds, and mechanisms.

Dassault Systèmes Announces Abaqus for CATIA V5 Version 2.3
These graphics are associated with the 06-July-2006 press release.
 Caption: View of a model of a composite airplane fuselage panel with point fasteners. Abaqus for CATIA V5 Version 2.3 provides a number of options for creating point, line, and surface-based connections between components. This fuselage panel contains a large number of flexible point fasteners that can be modeled rapidly using the spot weld tool. Connection tools such as this, together with Abaqus contact capabilities and the ability to simulate large deformation behavior, make Abaqus for CATIA V5 attractive for airframe and automotive body modeling.

| Caption: Abaqus Version 6.6 sets a new standard for accuracy in bolted-joint simulation without requiring a detailed model of bolt threads. These two images show the advantage of the new "smeared" bolt capability compared with a detailed thread modeling approach. At left is a stress contour plot that results if bolt threads are meshed in detail, which is a computationally prohibitive approach to bolt loading analysis. At right is a stress contour plot produced using the new thread-effects feature in Abaqus Version 6.6. The predictive results of the new solution correlate accurately to the results of the detailed thread model. |
