Do you want turning vanes with your duct work? Yes, if you are considering a square corner and you want to minimize your fan power requirement. Don't take my word for it, instead consider this Computational Fluid Dynamics (CFD) study that compares a vaneless square corner with both small turning vanes and large turning vanes.

Zoology professor Warren Porter leads a team of researchers from the University of Wisconsin-Madison that uses Computational Fluid Dynamics (CFD) to simulate heat transfer and drag. No big deal you say, until you hear that the subject of his CFD simulations is an elephant!
The next release of the Caedium CFD software system will include an enhanced Accuracy tool with a new maximum mesh size parameter. The new size parameter will provide a method to set an explicit physical element size for an entity (e.g., face) rather than just an interval (resolution) number as in the current version of Caedium.

After a thorough design review I decided to reverse the Questionable Approach applied to the Caedium interface described in "Counterintuitive Usability With The Questionable Approach". I think the April Fools' Day reality distortion field got the better of me. Rest assured that the next release of Caedium will have a new set of gorgeous different icons to compliment the new ribbon-like interface.

Researchers at the Media Attention Deficit (MAD) Lab recently reported findings that run counter to accepted norms in software usability design. The MAD Lab researchers found that the more difficult software was to use, the more memorable the software became. In light of this research we have replaced all the icons in Caedium with the same question mark icon in an effort to make our software more difficult to use, but easier to remember.
For the GPU Technology Conference 2013 (GTC13) I performed a series of simulations in Caedium comparing the OpenFOAM® linear solver GPU option using ofgpu with the standard CPU shared memory option using MPI. See selected slides and the presentation deck below.
