New FLUENT for CATIA V5 Extends CFD Modeling Capability

SOUTHPOINTE, Pa., April 17 /PRNewswire-FirstCall/ -- ANSYS, Inc.
(Nasdaq: ANSS), a global innovator of simulation software and technologies
designed to optimize product development processes, today announced the
release of version 4.0 of its FLUENT(R) for CATIA(R) V5 rapid flow modeling
software. This new release delivers class-leading computational fluid dynamics
(CFD) technology from ANSYS to engineers working within Dassault Systemes
CATIA V5 software environment. In addition to performance improvements, this
release of FLUENT for CATIA V5 adds important new physics models to its
analysis capabilities that extend the types of products for which performance
optimization is possible. The technology is a prime example of the ANSYS
ongoing commitment to an architecture that adapts to the customer's
requirements: developing integral tools for use by the world's leading
simulation community, no matter their choice of computer-aided design (CAD) or
product lifecycle management (PLM) packages.
Species transport and cavitation modeling capabilities are key new
features of version 4.0 that significantly broaden the range of applications
available to users. The new species transport model allows the modeling of
mixtures of fluids with different properties. This expands the types of
equipment that can be optimized to include paint mixers, fire risk detection,
airplane cabin ventilation, water treatment systems and the dispersion of
exhaust gases. The new cavitation modeling feature lets users predict when
cavitation may occur in a variety of systems. It allows performance
optimization of fuel injectors used in car and motorcycle engines. It also
lets users see when cavitation may occur in rotating pumps, enabling them to
make design modifications to reduce the blade erosion that may result. New
heat transfer boundary conditions let automotive companies model the cooling
of brake rotor disks, to ensure that optimum braking performance is maintained
under all conditions.
Version 4.0 brings many new important performance and usability
improvements. The ability to add multiple symmetry planes without the need to
modify original geometry saves users time, both while creating the model and
when performing the calculations. Superior flow volume splitting algorithms
benefit users who model automotive radiators and other complex geometries. A
new algorithm to build prismatic boundary layer meshes next to solids
increases the simulation accuracy; an example is the air flow around car
wheels. Other general improvements include an optimized memory management
system to handle large models efficiently and new options that let users
easily control the initial conditions for unsteady calculations. These
enhancements reduce the time to solution and improve simulation process
robustness.
"With the newly added features of version 4.0, FLUENT for CATIA V5 enables
users to improve designs quicker than ever using the power of leading
technology from ANSYS. No other engineering simulation software provider
offers such depth and breadth of technical capabilities," said Ferit Boysan,
vice president and general manager of the fluids business unit at ANSYS, Inc.
"FLUENT for CATIA V5 is unique in the industry because the embedded high-
fidelity FLUENT 6.3 solver provides the engineering organization full upward
scalability of their simulation process."
Version 4.0 of FLUENT for CATIA V5 is available for immediate shipment.
