Fluent is Given Prestigious Engineering Award
Posted Fri June 14, 2002 @02:06PM
Print version Email story Tweet story
News Fluent Inc. has been given a prestigious Engineering Heritage Hallmark Award for its innovation and excellence in mechanical engineering from the Institution of Mechanical Engineers.

The Award is the first ever to be given for software. Commenting on the award, Managing Director, Chris King said "I am delighted to see this recognition of the quality and impact of the FLUENT CFD software. The Institution of Mechanical Engineers is the UK's premier Mechanical Engineering forum. That they should have made the first such award for a software product to FLUENT is very special. In doing so they are recognising the contribution that the efforts of all sections of the Fluent organization have made to the establishment of CFD as an important engineering tool in so many industries."

Only two or three awards are given out annually from the IMechE. The criteria are strict and applicants must demonstrate industrial innovation and have made a significant contribution to mechanical engineering. Recent awards have been presented to organisations such as Rolls Royce, Eurostar and The Channel Tunnel.

Fluent's nomination for the award was supported by John Slater, Chairman of the Yorkshire Region of the IMechE, who adds "I was very happy to nominate the FLUENT software for the Heritage Award, it is a leading edge code that has inspired engineering students and commercial users for over a decade. It is a well deserved honor for the company and for South Yorkshire."

New Software: MayaVi-1.2 Released!
Posted Thu June 13, 2002 @03:37PM
Print version Email story Tweet story
Post Processing MayaVi is a free, easy to use, scientific data visualizer. It is written in Python and uses the Visualization Toolkit (VTK) for the graphics. It provides a GUI written using Tkinter. MayaVi is free and distributed under a BSD license. It is also scriptable and cross platform and should run on any platform where both Python and VTK are available.

For more information, downloadable sources and binaries, screenshots, installation instructions, documentation etc. visit the MayaVi home page on SourceForge.

Also bundled with MayaVi is a VTK pipeline browser written in Python and a new utility module that makes using VTK easier from the interpreter.

Changes: A license change from GPL/LGPL to BSD, a new interactive data picker and light manipulation kit, a new CellData to PointData filter, Geomview OOGL export support, a few more commandline options, important bugfixes, PDF documentation, and new RPMs and debs.

News Daat Research Corp. has added multiple processor capabilities to boost the calculating speed of its CFD thermal and flow analysis software, Coolit.

When installed into a multiple processor system, Coolit automatically recognizes the number of processors and parallelizes the computation accordingly. The result is a significant speed increase that ranges from a minimum of 1.5 times to almost double for dual processors. For more processors, speed gains are even greater.

This latest Coolit release, version 4.50, also incorporates numerous new features that aid the model building process and increase modeling accuracy. Most significant is the addition of new shapes to the component library. Tetrahedron, pyramid and spherical cap components join the previously released triangular prism components to make possible more complex shapes and more accurate geometries.

Other changes in the new release included greater editing flexibility, a wider range of component characteristics, and customizable projections in panel views. Coolit v.4.50 also implements a new advanced model for porous media. The new model is a significant improvement over the standard Brinkman model, which is used in most commercial CFD programs.

Coolit v.4.50 operates on all Windows-based platforms: Windows 95,98,2000,XP and NT. More information on Daat and Coolit can be found on the Daat web site.

News In a first for the product design industry, PTC announced its intention to support the Linux operating system for Pro/ENGINEER®. Pro/ENGINEER, PTC's flagship mechanical computer aided design (MCAD) application, gives users the power to create advanced, high-quality product models and designs that result in superior products. With the release of a Linux supported Pro/ENGINEER, PTC plans to accommodate the growing demand from top design engineers to support the Linux open-source operating system.

PTC also announced its intention to align with the Hewlett-Packard Company as the Linux partner for PTC's Pro/ENGINEER. Working with HP, PTC intends to support two popular Linux distributions, including Red Hat, on the full range of 32-bit Intel-based architecture workstations available from HP with the release of Pro/ENGINEER Wildfire later this year.

Now that there is reliable 3D OpenGL graphics hardware for Linux (thanks to NVIDIA), many more interactive engineering programs will be finding their way to Linux.

FLUENT Software Meets JSAE Benchmark
Posted Mon June 10, 2002 @04:51PM

News Earlier this year, the Japan Society of Automotive Engineers (JSAE) invited the major CFD software vendors who serve Japan's automotive industry to take part in a benchmarking exercise which tested CFD predictions on six classical automotive problems. Fluent Asia Pacific, Tokyo, Japan, using the worldwide company's flagship product, FLUENT, was one of the few companies to successfully complete all of the challenge problems with a high score.

The test cases included:

  • External aerodynamics
  • HVAC climate control in an automobile cabin
  • Static port modeling for internal combustion engine analysis
  • HVAC defrosting of an automobile windscreen
  • Automatic meshing capabilities
  • Visualization capabilities

    Although Fluent has numerous turbulence models and wall functions, the rules of the competition specified that participants use the default turbulence model without modifying any of the turbulence model constants. Fluent employed the realizable k-epsilon model throughout. Participants were, however, allowed some flexibility over the mesh design. A tetra mesh with a hybrid prism near the surface proved to be most popular.

    In addition to checking the accuracy of the solutions against experimental data, the calculation speed and memory requirements were also taken into consideration. In all these important areas, FLUENT performed well. A full description of the results is available from the Japanese Society of Automotive Engineers.
