Dassault Systemes Announces Major Advancements in New Abaqus Release from SIMULIA

Unified FEA Technology Accelerates Industry Use of Realistic
Simulation to Evaluate Products, Materials, and Processes
PARIS & PROVIDENCE, R.I.--(Business Wire)--
Regulatory News:

Dassault Systemes (DS) (Paris:DSY) (NASDAQ:DASTY), a world leader
in 3D and Product Lifecycle Management (PLM) solutions, today
announced the availability of Abaqus 6.8, its technology-leading
unified finite element analysis (FEA) software suite from SIMULIA.
Engineers, designers, researchers, and scientists use Abaqus to lower
costs and reduce cycle times through the realistic simulation of
stress, impact, crush, fluid-structure interaction, thermal dynamics,
and other complex behaviors of products, materials, and processes.

With a focus on solving specific engineering challenges in
automotive, aerospace, electronics, energy, packaged goods, and other
industry segments, Abaqus 6.8 provides new and improved capabilities
in core areas, including modeling and results visualization,
structural analysis, composites failure, general contact, computing
performance, and multiphysics.

"Abaqus FEA software provides the robust contact capabilities that
we need to study complex loading and structural interactions while
designing our large, two-stroke diesel engines," stated Per R0nnedal,
senior manager, R&D new design, MAN Diesel. "With the new capabilities
in Abaqus 6.8, we have seen memory usage significantly reduced when
running linear static analyses with multiple load cases. These
improvements will allow us to test a number of design alternatives to
optimize our diesel engine performance during early product
development."

"This latest release of Abaqus Unified FEA software is another
milestone in our long history of developing simulation technology that
accelerates our customers' evaluation of real-world behavior of their
products and processes," stated Steve Crowley, director of product
management, SIMULIA, Dassault Systemes. "With literally hundreds of
new features and customer-requested enhancements, Abaqus 6.8
demonstrates SIMULIA's commitment to technical excellence,
industry-focused solutions, and customer satisfaction."

Designers and engineers in all industries are able to leverage
Abaqus 6.8 to deepen their knowledge of real-world structural behavior
and accelerate the development of innovative products. Among the
latest advancements are:

-- Fully built-in and improved composites analysis capabilities
that enable aerospace engineers to efficiently simulate the
behavior of composite crack propagation, delamination, and
possible failure.

-- Industry-unique capabilities that allow automotive engineers
to capture full-vehicle noise and vibration response due to
tire rolling effects and viscoelastic material effects from
tires, bushings, isolators, and laminated steel.

-- A low-cycle fatigue method that assists electronics engineers
in assessing the lifecycle of solder joints. This method is
also useful for evaluating powertrain durability and bone
degradation in biomechanical applications.

-- A new anisotropic hyperelastic material model that enables
medical device developers to simulate soft tissue interaction
with stents and orthopedic implants. This model can also be
used to analyze materials such as reinforced rubber and wood.

-- A new Coupled Eulerian-Lagrangian (CEL) multiphysics
capability that allows industrial equipment manufacturers to
predict loads on earth-moving equipment during soil
excavation. The capability can also be used to predict the
behavior of fluid-filled containers, hydroplaning tires, and
bird-strike on aircraft.
