Congratulations to FY Fluid Dynamics‘ 3-year anniversary.The EnSight blog shares the news that NAFEMS is looking for someone to write a book on CFD postprocessing.A preliminary list of presenters and topics is available for the next Open Source CFD International Conference.Submit an image by 31 August for CD-adapco’s 2014 calendar contest and maybe you’ll win an iPad mini.Autodesk wants to hire a Product Manager Simulation CFD in Charlottesville, VA.Touching on some of the same topics as the “dangerous CFD” discussion, Tech4PD Episode 11 features a debate on exactly where and how early in the design process simulation should be introduced.

How Far Upstream Should Simulation Be Performed? What do you think? Comment here or at DE or on LinkedIn. It implies an organization that’s made the appropriate investment in tools and training and validation and verification. Implicit in all of this is the user’s responsibility to know what they’re doing and to have sufficient knowledge of engineering fundamentals to know if the answers being computed are – if not good – not bogus. It’s not risky, but it’s not easy either. It is not risky to develop and deploy CFD tools that can be applied by non-analyst engineers. These three interpretations are why I don’t think it’s dangerous to simplify CFD for the masses. He’s simply referring to all the engineers out there who could benefit from the use of simulation but don’t know what a Hessian is.

Masses – Whenever I read “masses” used in this context I’m reminded of the inscription on the Statue of Liberty that reads in part “Your huddled masses yearning to breath free / The wretched refuse of your teeming shore.” I’m fairly certain Kenneth isn’t comparing non-expert CFDers to “huddled masses” or “wretched refuse.” Nor do I think he believes CFD needs to be used by the random person on the street. Nor should I have to know what a Hessian is to run a CFD code. For example, I don’t have to be Mario Andretti to drive my car. I’m certain he means the development and deployment of CFD tools that don’t require a PhD and years of solver algorithm development experience to use. Simplify – One might be tempted to think that by simplify Kenneth means the reductio ad absurdum of CFD into a toy. Wrong answers introduce risk into the design and manufacture of products. If on the other hand Kenneth is using dangerous as a synonym for “risky” then there’s certainly always the risk that CFD will result in wrong answers. Before answering, let’s dissect and defuse Kenneth’s word choices.ĭangerous – Driving a car may be the most dangerous thing any of us do because it carries with it the constant threat of death, serious bodily harm, and expensive property damage.

The original author, Kenneth Wong, worded the question masterfully to maximize the debate. Īgree or disagree: It’s dangerous to simplify FEA and make it accessible for the masses.
