Dassault updates Abaqus FEA suite
A
Dassault Systemes product story
Edited by the Engineeringtalk editorial team
May 27, 2009
Dassault Systemes has introduced Abaqus 6.9, a unified finite element analysis (FEA) product suite from Simulia.
Abaqus is used by designers, engineers and researchers in industries such as electronics, consumer packaged goods, aerospace, automotive, energy and life sciences, to evaluate real-world behaviour of materials, products and manufacturing processes.
This release delivers new capabilities for fracture and failure, high-performance computing, noise and vibration.
Simulia has also enriched the product suite with capabilities for modelling, meshing, contact, materials and multi-physics.
Abaqus 6.9 lets manufacturing companies consolidate nonlinear and linear analysis processes within a unified FEA environment.
The Extended Finite Element Method (XFEM) in Abaqus simulates crack growth along arbitrary paths that do not correspond to element boundaries.
In the aerospace industry, XFEM can be combined with other Abaqus capabilities to predict the durability and damage tolerance of composite aircraft structures.
In the energy industry, it can help evaluate the onset and growth of cracks in pressure vessels.
The general contact implementation offers a simplified and automated method for defining contact interactions in a model.
This capability provides substantial efficiency improvements in modelling complex assemblies such as gear systems, hydraulic cylinders, or other products that have parts that come into contact.
A new co-simulation method lets users combine the Abaqus implicit and explicit solvers into a single simulation, which reduces computation time.
For example, automotive engineers can now combine a substructure representation of a vehicle body with a model of the tires and suspension systems to evaluate the durability of a vehicle running over a pothole.
Abaqus/CAE provides faster, more robust meshing and powerful results-visualisation techniques.
The AMS Eigensolver improves the efficiency of large-scale linear dynamics workflows used for applications such as automotive noise and vibration analyses.
A new viscous shear model allows the simulation of non-Newtonian fluids such as blood, paste, molten polymers and other fluids often used in consumer product and industrial applications.
