August 2015: Are You Ready For CFD?

You've heard that Computational Fluid Dynamics (CFD) might be able to help with your fluid dynamics application, but you are unsure how to proceed. Then fear not, we've got you covered this month with articles on how to get started with CFD and clarifications on our Caedium CFD offering. Also, see whether CFD has a role in drone design.

Get Started With CFD

New to Computational Fluid Dynamics (CFD)? Then you've come to the right place. Becoming productive in CFD can be a daunting task. However, as with all long term goals, if you break it down into smaller, achievable tasks, in no time you'll be up to speed and ready for production level work. Assuming you are familiar with the fluid dynamics of your application, then let's begin.

July 2015: Summer Cycling, Support, and More CFD Fun

Summer's here at Symscape HQ and therefore it's Tour de France time, so find out why cycling has gone all in on aero. Unrelated - but an important issue - do you know why Computational Fluid Dynamics (CFD) can be so costly? If not, learn more about the role of technical support. Then to finish up with even more fun than last month, see how Caedium simulated the flow through the pipe networks from a classic screensaver of yesteryear.

CFD Support Worth Paying For

Computational Fluid Dynamics (CFD) software is not like other desktop applications, such as a word processor. Using a word processor to write a novel is usually undertaken without expecting that the word processor software vendor to also provide help constructing sentences and paragraphs. Yet in the CFD industry that is exactly the expectation (need) of CFD users, i.e., CFD users expect help from a CFD vendor on how to construct a model (sentences) and run a simulation (paragraphs).

Pipe Fun With CFD

After replicating the classic pipes screensaver in Caedium for fun, the next obvious step was to run Computational Fluid Dynamics (CFD) simulations for each pipe network to ramp up the fun even higher.

June 2015: Unstructured CFD Learning and Productivity

Do you find the thought of Computational Fluid Dynamics (CFD) too daunting? Then read about unstructured learning, otherwise known as play! Next, step up your CFD productivity with some complimentary app suggestions. Finally, with your newly honed skills and productivity, find out how to make a difference in the design process by recognizing and targeting strong form CFD.

Learn CFD Through Play

Rather than wait until your project schedule dictates it's time for Computational Fluid Dynamics (CFD) analysis, allocate time now to 'play' with CFD. By 'play' I mean construct simple geometry and keep your cases relatively small, so you can get familiar with the basic features of your particular CFD software in a timely manner.

Weak and Strong Form CFD

If you are given production-ready detailed CAD geometry (nuts, bolts, and all) for Computational Fluid Dynamics (CFD) analysis you have to ask yourself, is this really an engineering endeavor or a marketing exercise? Given the effort to produce a complete, detailed CAD model, it is unlikely that any significant changes will be looked upon favorably. Instead you will likely find that CFD is to be used in its weakest form, i.e., Colorful Fluid Dynamics (CFD) for marketing.
