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.

Niklas Wendel and Julia Gundert, students at Thomas-Morus-Gymnasium, Daun, Germany, recently completed a project to envisage an airliner of the future with a focus on sustainability and fuel efficiency. Their project was named HELT, translated as a German acronym for 'High Efficiency Aircraft', and is also similar to the German word 'held' which translates to 'hero' in English. During their early concept design phase they used Caedium Professional to perform Computational Fluid Dynamics (CFD) simulations to evaluate the aerodynamic efficiency of various configurations before selecting their final Blended Wing-Body (BWB) design.

Computational Fluid Dynamics (CFD) sees broad use in many applications across a diverse range of industries. No more so is this true than in the applications you'll see for CFD in external aerodynamics analysis.

You probably know that the Navier-Stokes (NS) equations are named after Claude-Louis Navier and George Gabriel Stokes. Navier come up with the first original derivation based on discrete molecular interactions (discrete approach) and Stokes originated the assumption of a continuum directly using viscosity that is the widely referenced approach still taught today. However, between these two approaches there were other derivations, a continuum of sorts, attributed to other luminaries of 19th Century science.
