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.

November 2014: What can CFD do for you?

What has Computational Fluid Dynamics (CFD) done for you lately? Or more to the point - what can CFD do for you? For a brief reminder of the broad range of internal and external CFD flow applications, and for a specific external aerodynamics case study, read on.

Heroic Aircraft Design Aided by Caedium CFD

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.

Internal Flow with CFD

Just as Computational Fluid Dynamics (CFD) has found extensive use across a wide range of external flow applications, it is also used to simulate a diverse set of internal flow applications.

External Aerodynamics with CFD

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.

October 2014: The Founding Fathers of CFD

The theory on which Computational Fluid Dynamics (CFD) depends was laid way back in the 19th Century, before the dawn of practical computers. Take a moment to marvel at some of the science pioneers armed only with pens and paper who enabled CFD to become an essential engineering tool used today by a wide swath of industries.

September 2014: Geometry Techniques for CFD

The overwhelming majority of issues that prevent a smooth Computational Fluid Dynamics (CFD) process are related to geometry. If geometry issues cause you headaches, then read on for a series of articles that describe techniques to help you navigate around common problems. Once you are done, unwind with a look at how nature uses similar visualizations to those found in CFD.
