Civil Protest Against CFD?
Posted Mon September 08, 2003 @08:44AM
Print version Email story Tweet story
News Last week a group of people staged a protest outside Fluent's Sheffield, UK offices. Citing Fluent's "use of software for airflow modelling of missiles", the group was more likely trying to gain pubilicity for themselves by staging an early protest against this week's DSEi defense conference in London, of which Fluent is an exhibitor.

According to this report, four people barricaded a revolving door, two others locked themselves to the door using bicycle locks, and others hung banners including "Fluent Deal in Death" on the main entrance.

Police failed to stop the action because "work was not stopped" (a backdoor remained open), however, they are fortunate that an emergency did not occur in the building with the main entrance blocked.

Civil action has its place, but it is clear that this group is misguided -- another website reported the action as "Sheffield Arms Traders Targeted".

CFdesign Blue Ridge Numerics Inc. announces that it has been named to Deloitte & Touche’s Technology Fast 50 Program for Virginia, a ranking of the 50 fastest growing technology companies in the area by Deloitte & Touche. Rankings are based on the percentage of growth in fiscal year revenues over five years, from 1998-2002.

Blue Ridge Numerics has grown its operating revenues over the past five years by 415% while other computer-aided engineering software companies have struggled to sustain even modest growth. The company’s success is attributed directly to the increasing popularity of CFdesign, its flagship software product.

CFdesign is virtual prototyping software that saves companies money and time by reducing the amount of wind tunnel and flow bench testing necessary to validate new designs.

CFD and FEA Meshing Overview
Posted Thu September 04, 2003 @08:53AM
Print version Email story Tweet story
Grid Generation Mechanical Engineering magazine has posted an overview of grid generation for FEA and CFD analysis. "making a mesh of things" covers developments in meshing in the last few years and explains the trade-offs associated with "simple meshing".
Pre-processing mesh technologies can now automatically generate the mesh necessary for analysis. Like most things, this is both good and bad. It means that expert analysts need not be involved in simple analysis, but it also means the software design engineers can run analyses without fully understanding FEA methodology, which could affect design.

ANSYS CFX CFX recently joined the ANSYS family to incorporate state-of-the-art CFD technology into the ever-growing ANSYS suite of simulation solutions. As a long-standing strategy, ANSYS strives to provide a robust multiphysics capability that enables companies to simulate the performance of complete products in their intended environment.

With CFX, increasingly powerful simulations are available throughout all stages of the product development process.

A wide variety of industries have already benefited from this technology, you should too!

To learn more about how ANSYS, ICEM CFD and CFX software are evolving together, join us for a live web seminar on September 3 or September 17 at 1 pm EDT.

In addition, join us September 25 or October 23 at 2 pm EDT for a live web demonstration of CFX-5 in action. For those unfamiliar with CFX-5, this demonstration illlustrates why CFX-5 is the best-in-class CFD software available today. Features of CFX-5 to be demonstrated include grid adaption, parallelization set-up and CFX Expression Language.

Visit the seminar website to register.

Sorry, these events are only available in North America.

AVL AVL FIRE Workshop
Focus: Exhaust Gas Aftertreatment Simulation

More stringent emission requirements demand new approaches to the design and layout of off-gas treatment systems. The advanced concepts in this field require simulation tools to characterize performance and help engineers integrate catalytic reactors and filtration units into today's vehicles.

The FIRE Aftertreatment module fulfills this requirement by offering the most advanced aftertreatment-specific physical models, unparalleled flexibility and full coupling to FIRE's renowned engine analysis capabilities.

AVL is pleased to invite you to a one day AVL FIRE workshop to be held on September 23rd, 2003 at Chalmers University of Technology in Gothenburg, Sweden.

Besides the main focus on AVL´s exhaust gas aftertreatment solution, there will be sufficient time to explore the new features of our CFD code FIRE, including:

  • unrivaled meshing concept
  • a completely new solver technology
  • fast and versatile result data exploration

Generally, no specific knowledge of FIRE is required, however a general understanding of engineering workstations and fluid mechanics is necessary to gain most benefit from the workshop. Number of participants will be limited, so please register soon.

Help With Bubble Column Simulation
Posted Fri August 29, 2003 @03:39PM

Help Desk Paraphrased from a comment to an article:

I have scaned your post on bubble column simulation by fluent in May. Now I have the similar question with you. I guess you must have solved the problem.I am a newer for fluent. My simulation can not be converged. For there are some many parameters, I can't find what's the wrong, could you send me a sample case file for bubble columne by fluent? By comparing that, I may find my wrong. I hope you can help me. Thank you very much! My e-mail address: zhsnaky@yahoo.com
