Print version Email story Tweet story
News ANSYS and ICEM CFD Engineering have announced the ICEM CFD European User Meeting. Over the last year many new features have been added to the core ICEM products and several new 'Vertical Applications' have also been introduced.

With the launch of ICEM CFD version 5 expected later this year now is an excellent opportunity to see what's coming and to discuss your future requirements directly with ANSYS / ICEM CFD Engineering.

The meeting will cover new features and products as well as user presentations and will give you the chance to meet fellow ICEM users from all over Europe.

New Software: FLUENT 6.1 Released

ANSYS FLUENT Fluent Inc. has announced the immediate availability of version 6.1 of its Computational Fluid Dynamics (CFD) software, FLUENT(r). This major release offers several key functionality advantages to FLUENT users, including dynamic mesh for modeling flow conditions in and around moving objects. This easy-to-use capability allows users to simply set up the initial mesh, prescribe the motion, and sit back and watch as FLUENT automatically changes the mesh to follow the motion.

"The new dynamic mesh modeling capability reaffirms our history of innovation," says Fluent's Chief Technology Officer, Dipankar Choudhury. "FLUENT can now easily simulate physical phenomena previously requiring tedious manual preparation. Applications for this new capability include the modeling of automotive in-cylinder flows, store separation and missile launches, moving valves, fuel injector pumps, and mixing equipment. But, really, the applications for this are limitless. Our customers are thinking of new ways to use it all the time," he adds.

Application: Validating CFD with Tomography
Posted Mon March 17, 2003 @02:23PM

Application e3engineering.com has posted an article on the use of CFD to reduce the pressure drop across a fixed catalyst bed reactor by Manchester, UK based ITS.

Initial predictions of the internal flow patterns through the new reactor design were made using a CFD package and gave favourable results. But in many situations CFD models are difficult to validate, and the internal design of this particular catalyst bed, with a non-uniform porosity, made it particularly hard.

In this case, engineers performed validation of the CFD results using electrical resistance tomography (ERT) which uses instantaneous bursts of current to measure the conductivity of the fluid at a plane in the vessel. By injecting a higher conductivity fluid as a tracer and watching it progress through the vessel in time, engineers are able to measure mixing within the vessel.

Combining ERT results from multiple planes of the electrode array produces results which are a reasonable match with the CFD predictions.

Grid Generation The 12th International Meshing Roundtable will be held in Santa Fe, New Mexico, USA, on September 14-17, 2003.

In 1992, Sandia National Laboratories started the Meshing Roundtable as a small meeting of like-minded companies and organizations striving to establish a common focus for research and development in the field of mesh and grid generation. Sandia National Laboratories continues to organize the International Meshing Roundtable, which has become recognized as an international focal point annually attended by researchers and developers from dozens of countries around the world. The relaxed atmosphere at each Roundtable provides an open and technically rich environment in which to share new ideas and technical advances.

The International Meshing Roundtable continues to focus on bringing together researchers and developers from academia, national labs and industry in a stimulating, open environment to share technical information related to mesh generation and general pre-processing techniques. In 2003, Roundtable attendees will enjoy Santa Fe's unique Southwest architecture, picturesque streets, Loretto Chapel and miraculous staircase, distinctive regional foods, fine museums and art galleries. Santa Fe is filled with 400 years of history and culture. The conference hotel, Inn at Loretto, is within walking distance to the plaza, Palace of Governors and other attractions.

Research: Pointwise Heads Unstructured Meshing R&D Project
Posted Fri March 14, 2003 @03:06PM
Print version Email story Tweet story
Grid Generation Pointwise, Inc. has been awarded a research and development contract worth an estimated $500,000 from the United States Air Force Research Laboratory (AFRL) for the development of an application programming interface (API) for unstructured meshing. Work on the 24 month research project, titled Geometry and Grid Modeling for Numerical Simulation (GGMNS), began in November 2002.

The goal of the GGMNS project is to develop an API to serve as a programming guideline for researchers developing new unstructured meshing techniques. AFRL and other agencies often fund such development with the hope that the new techniques will be incorporated into meshing applications for the benefit of the end user. However, without a standard API, the software implementation of meshing research often requires considerable rework for integration into existing software. The rework is often sufficiently large that integration is never attempted or completed, and the end-user never benefits from the results of the research. A standard API would also benefit meshing researchers by allowing them to use existing meshing applications as frameworks for their research, rather than spending resources developing their own application frameworks.

News Blue Ridge Numerics will begin a 19 city seminar tour this week for product development engineers and engineering managers.

This educational and interactive seminar provides an up-close look at how a new generation of engineers is using CFdesign as an extension of their 3D MCAD system to optimize fluid flow and heat transfer performance.

Companies using CFdesign report that on average they are able to reduce the time it takes to develop an optimized product design by 70% while cutting department-level costs by 65%.

"For most engineers, CFD has never been a realistic option because it imposes too many barriers on the product development process," explains Jim Spann, Blue Ridge Numerics' vice president of marketing. CFdesign has knocked down all these barriers and companies are eager to get an up-close look at this revolutionary technology. Local market seminars are a great way to get a thorough introduction."
