This Week in CFD

Still catching up with the backlog of CFD news but there’s a lot of good stuff including a new Lattice-Boltmann method, several open positions for those of you who are looking, financial updates from several companies to assess how they’re weathering the macroeconomic slowdown, a glowing review of Discovery Live, and a multiphysics simulation of the sound an electric guitar string would make when plucked. Shown here is a FieldView visualization of helicopter downwash from their presentation at the Altair Technology Conference.

Jobs & Stevies

[Given IMO the lack of decent CFD images in this week’s roundup of CFD news I decided to go with this.] This graphic celebrating the USAF’s 73rd birthday has two notable features. First, the faceted background. Second, the aircraft featured. Coming on the heels of a statement that a a prototype of the Next Generation Air Dominance aircraft (i.e. the F-22 replacement) has already been flown, folks are speculating that this is that prototype.

The Geometric Meets the Organic

The tension between the geometric and the organic is palpable in Sipho Mabona‘s origami-inspired, cotton-based works. The cotton sheet, the natural dyes and the frayed edges bring softness to the otherwise hard-edges, so much so that it imparts a strong desire to touch the work.

Form and color are never separate and Mabona’s folded third dimension brings light and shadow into the image, elevating the simple to the sublime.
