Simulation For Your 3D Printer

3D printers are the new black.

Whether 3D printing can live up to the hype remains to be seen. However, making things has been around since time eternal. The fact that 3D printers have reached a price point allowing small businesses and hobbyists, collectively referred to as Makers, to leap on board is definitely exciting. However, what hasn't changed is that building a physical thing still costs time and money. What can we learn from the millennia of building things prior to the availability of 3D printers?

Helical Strakes with your Chimney?

Helical strakes are often used on chimneys to reduce vortex induced vibration (VIV). However, these strakes also have a significant drawback - they induce massive increases in drag and side forces that have significant structural implications for the chimney. Read on for a Computational Fluid Dynamics (CFD) study that compares a smooth cylindrical chimney to the same chimney with helical strakes.

Turning Vanes Required

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.

Elephants and Computational Fluid Dynamics

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!

Caedium v5 Sneak Peek: 3Dconnexion 3D Mouse Support

The next release of the Caedium CFD software system on Windows will support the 3Dconnexion family of 3D mice.

Caedium v5 Sneak Peek: Enhanced Accuracy Tool

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.

Questionable Approach Reverse

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.

Counterintuitive Usability With The Questionable Approach

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.

CFD Performance Comparison Between GPU and CPU

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.
