This Week in CFD

hexalab-smallThis week’s CFD news is less inscrutable than the Great Sphinx of Giza (shown here courtesy of the must-try new tool for mesh viz in your  browser, HexLab) and includes several recently announced events, a new CFD startup (AirShaper), and our old friend democratization is back. Read all the way to the end for a brain teaser on cutting a tetrahedron.

Events

HexaLab is a new, free, online tool for examining hexahedral meshes. The image shown above is one of their sample cases with scaled Jacobian begin examined running in Chrome on my Windows 10 laptop. Read about HexaLab here. [Very cool]

Pointwise offers the on-demand webinar “Meshing Automation and Adaptability in Pointwise V18.1” which will demonstrate the new features introduced into this new version of the software.

Serendipity in Artlanta

My fellow art maven, Bob, and I were thwarted in our commitment to escape conferences for a brain-cleansing visit to the local art scene. Atlanta, site of AIAA Aviation 2018, is home to the High Museum of Art. Unfortunately for me and Bob, the museum’s modern and contemporary galleries were closed for renovation during our visit to the city.

Serendipity replaced thwartage while hustling to make my flight at ATL when I passed through a hallway decorated with artworks on both walls, including a painting on wood relief panel by Will Penny titled Gamut Relief XIII with an obvious and pleasing 3-D mesh motif.

Upon returning to the office I searched online for more of Penny’s work and found several including the very similar work shown below. From the brief description at that website, Penny is said to be “exploring tensions between tangible space and the impact of digital technology on fabricated forms and environments.”

Bonus: Do you know how to cut a regular tetrahedron in a way that produces a square? Think about it before clicking through.
