Fluid Device Design is Like Herding Cats So Let CFD Help

Where the action of a fluid is the primary concern in the design of a device, e.g., a cyclone, sometimes it can seem that fluid is going out of its way to be difficult - a lot like trying to herd cats. Fluid device designers have to carefully match geometry to flow rates to meet performance criteria. However, if they were to rely solely on physical testing, then their task is that much harder and more costly because they can't easily visualize the flow behavior. Let Computational Fluid Dynamics (CFD) save you money and time as a supplement to physical testing.

Reduced Complexity 3D Models for CFD

Reduced complexity 3D model for Computational Fluid Dynamics (CFD) is a great way to avoid getting bogged down in details that are not relevant for a simulation. 3D video games and 3D animation applications have been using reduced complexity 3D models combined with texture maps to present rich visuals since the dawn of the digital age. These models and the concepts to build them can be extremely useful for CFD.

December 2014: Holiday CFD Doodles

The festive holiday season is once again upon us. What better way to mark the occasion than with a Computational Fluid Dynamics (CFD) doodle. No ordinary doodle though, a mega snow globe CFD doodle. Many a doodle has preceded a great innovation, so get your CFD doodle on and share your Caedium CFD doodles with us. Not sure if CFD doodling is for you? Then check out my latest blog posts that include the top 5 reasons to try CFD and why not all CFD GUIs are equivalent. Finally, I'd like to wish you a Merry Holiday and a prosperous New Year.

CFD Doodle: Multiple Interconnected Snow Globes

It's not just Google that can doodle. The Computational Fluid Dynamics (CFD) community on occasion has also been known to embrace its whimsy side, especially during holidays, and so I give you a CFD doodle. For fluid dynamicists (or at least this one) the snow globe has always had a special attraction and if one is good then four has to be awesome, right?

Not All CFD GUIs Are Created Equal

Given the adoption and success of modern GUIs across a broad range of software, you'd think that making the case for one would be redundant. However, for some reason Computational Fluid Dynamics (CFD) was a late adopter of GUIs, and for what is predominantly a visual set of disciplines - think geometry, mesh, solver feedback, 3D visualization, and 2D plots. This late adoption is still evident in CFD software today.
