Computational fluid dynamics software enhances simulation, boosts productivity
Mentor, a Siemens business, has released the latest version of its frontloading FloEFD computational fluid dynamics (CFD) code with new functionality for geometry handling, physics and results visualization. As well as a stand-alone version, FloEFD is embedded in popular CAD tools including Siemens NX, Solid Edge, Creo, and CATIA V5

Featuring intelligent technology enabling fast and accurate simulation, the FloEFD solution helps users ‘frontload’ CFD simulation early into the design process to understand the behaviour of their concepts and eliminate the less attractive options. The FloEFD product can reduce the overall simulation time by as much as 65-75% and offers 2x to 40x user productivity enhancements. This helps engineers in the automotive, aerospace, electronics and industrial equipment markets optimize product performance and reliability and reduce physical prototyping and development costs.

 

Added is free surface simulation functionality enabling users to simulate surface flows to observe fluid movement, such as flow of liquids into a storage tank. This important feature is useful for food and beverage processing equipment as well as automotive, and military/aerospace. The FloEFD product also includes sector periodicity, an efficient geometry handling feature, which allows users to model only a fraction or section of large cylindrical shapes. This functionality helps reduce the model and mesh size, enables faster analysis and is especially useful for industrial design applications such as turbo-machinery, pumps, fans and compressors.

 

Enhancements to the LED module have also been made. Radiation spectrum and setting intensity of radiation dependent on the angle can be defined. As a result, the FloEFD product can automatically apply the calculated radiant flux on top of an LED. Also, its FloEDA Bridge allows users to import EDA geometry into CAD with different levels of geometry resolution from compact to fully explicit including all the layers and vias. With the latest release, in addition to the geometry, material properties and heat power can be added to the FloEFD simulation. A powerful stand-alone viewer is now offered by FloEFD to help engineers share analysis results with those who do not have a copy of the FloEFD product. For example, an engineer can use the viewer to share the analysis results with clients or group managers for final approval.
