Print version Email story Tweet story
ANSYS FLUENT Fluent has announced the release of the latest version of their general purpose pre-processor for CFD. GAMBIT 2.0 features an updated geometry kernel which allows for direct access to Pro/ENGINEER's geometry engine and support for ACIS 6.3.

Also new to this release is GAMBIT's ability to automatically refine the mesh in areas of strong curvature and near small gaps. An example of this technology was displayed in the IMR Meshing Maestro award-winning mesh.

A new version of G/Turbo has also been released with GAMBIT 2.0. G/Turbo is an application specific pre-processor integrated into the GAMBIT interface. G/Turbo is a tool which enables the rapid generation of meshes for turbomachinery applications. A unique feature of the pre-processor is the ability to create both structured and unstructured meshes. This allows simple geometries to be created very quickly while also providing a path for analysis of more complex models. G/Turbo is supplied as an add-on to GAMBIT 2.0.

CD-adapco adapco and TTF have announced the signing of a worldwide partnership agreement which will enable STAR-CD to read native CAD formats.

Trade and Technologies France SA (TTF) develops and markets solutions for CAD model interoperability. adapco will integrate TTF CAD libraries into their software for reading the native formats of the major CAD systems independently of the CAD license.

"We are looking forward to working with TTF towards our goal of bringing our CFD tools more truly into the CAE design engineering environment than has ever been achieved in the fluid flow simulation market", said Steve MacDonald ,chief executive of the CD adapco Group.
There is no word as of yet which CAD formats will be supported, however, TTF claims library support for CATIA, PRO-ENGINEER, UNIGRAPHICS, CADDS, and EUCLID.

CFX Launches New Maritime Competence Centre
Posted Thu January 03, 2002 @06:58PM
Print version Email story Tweet story
ANSYS CFX CFX-Germany has teamed with Schiffbau-Versuchanstalt Potsdam GmbH (SVA) to form a "Maritime CFX Competence Centre". Building on a well-established relationship, the partnership is focused on improving understanding of the unsteady flow past a the propeller as it rotates behind the ship.

Previous simulations of the propeller-ship configuration have shown that a true time-dependent rotor-stator interface provides a significantly higher level of accuracy than steady-state simulations using a sliding mixing plane. The unsteady approach also provides pressure fluctation data on the hull and rudder which are a main source for noise and vibration within the ship.

The new work allows ship hulls to be optimized based on not only their drag, but also on the interaction of the propeller and hull. This will allow for designs which can achieve a desired speed at a lower power requirement.

"The collaboration between SVA and CFX has resulted in many significant improvements of the CFX software, which makes CFX the preferred choice in marine applications. We are committed to ensuring our software meets the demands of our maritime customers," endorses Florian Menter, Head of Development at CFX-Germany.

Hanley Launches Complete 3D Wing Design and Analysis
Posted Tue January 01, 2002 @06:15PM

News Patrick Hanley, Ph.D. writes "OCALA, Florida, December 31, 2001 - Hanley Innovations, a small business specializing in aerodynamics and fluid dynamics software development for education and industry, announced today the release of WingAnalysis Plus, Version 1.1 for Windows 95/98/NT/2000/XP.

WingAnalysis Plus can be used by manufacturers, engineers, kit plane builders, students and others to design and test 3-D wings. This unique software allows the user to seamlessly combine airfoil shapes and wing planform dimensions to perform a complete 3-D wing analysis. The software can test custom airfoils and has a built-in library of over a thousand airfoil shapes including NACA 4, 5 & 6-digit airfoils, Eppler, GAW and many others suitable for a variety of mission critical tasks.

WingAnalysis Plus 1.1 is an essential design and reference tool for engineers and designers who need a readily available database of airfoils for wings and other aerodynamic surface designs. Kit plane builders can test and compare wings with different airfoil shapes at the roots & tips, aspect ratios, taper ratios and twist. Automotive engineers can use WingAnalysis Plus to compare performance data for automobile spoilers (without ground effect). It is also useful to marine design engineers who need to select and analyze foils for keel, rudders and centerboards.

WingAnalysis Plus 1.1 can be used to compute the lift, drag and moment generated by wings at a specific angles of attack and to estimate their stall angles of attack and maximum lift values. The software can generate lift and drag polar graphs; plot multiple curves to compare wing performance; generate lift versus angle of attack graphs and print out tables of design parameters. WingAnalysis Plus can export airfoils to .DXF files for use in other CAD programs; export airfoil coordinates to ASCII files; and plot airfoils to any dimension using your windows support printer.

The cost of a single machine license of WingAnalysis Plus is $895.00 US and it can be purchased and obtained over the internet from the following url: http://secure.emetrix.com/order/product.asp?PID=31 6301&q=1.

More information about WingAnalysis Plus and other software can be found at Dr. Hanley's www site. The URL is http://www.hanleyinnovations.com.
