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.
