Ansys Inc. has released Version 4.0 of its FLUENT for CATIA V5, an upgrade to its computational fluid dynamics (CFD) tool that offers new capabilities for engineers working in Dassault Systemes’ popular 3-D CAD environment.
FLUENT for CATIA V5 offers performance improvements along with new physics models that extend the analysis capabilities to different types of products. For example, a new species transport model allows the modeling of mixtures of fluids with different properties, making the tool well suited to handle analysis of equipment like paint mixers, fire risk detection systems, airplane cabin ventilation and water treatment systems. A new cavitation modeling feature will allow for performance optimization of fuel injectors used in car and motorcycle engines, along with rotating pumps. New heat transfer boundary conditions let automotive makers model the cooling of brake rotor disks.
Other improvements include optimized memory management for handling large models more efficiently, usability improvements and new algorithms to boost performance.
Design engineer compensation varies widely by location. If you live in Boston, your salary will average more than $90,000, nearly $20,000 above the national average. But if you live in Cleveland, your salary will average almost $10,000 below the national average.
For many years, it was believed that the strongest biological substance on Earth was spider silk, but new research says aquatic snails produce an even stronger material that could disrupt manufacturing forever.
Most everyone thinks they are ready for an emergency or a disaster. Most everyone is wrong. But engineers are a unique position here as both the designers and beneficiaries of emergency preparedness systems.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
