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 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.

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?

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.
