This Week in CFD

Special “Happy Birthday to ‘Murica” Version

News

  • DEVELOP3D writes about running SolidWorks in the cloud using NVIDIA’s Grid Test Drive.
  • Congratulations to Altair for being recognized as a 2014 Michigan Bright Spot, helping drive forward the state’s economy and innovation.
  • Do you find the Jacobi Iterative Method more useful now that it’s been sped-up by a factor of 200?
  • Read about how Autodesk Simulation CFD is used to design large video displays and related devices. (PDF)
  • More reading, this time about grid generation for near-field sonic boom prediction.

Even More News

  • NASA’s CFD 2030 Vision Study has everyone [meaning me – you were probably already thinking about it] thinking about exascale computing. Scientific Computing World has a nice overview article on Exascale Challenges. Some interesting [to me] factoids include:
    • An exaflop is a billion billion operations per second. That’s what we in science call “a lot.”
    • How will we program applications that have billions of threads? And how will we do so in a way that’s robust?
    • Who is going to do all this programming? It’s not within the typical CFD programmer’s skill set.
    • Power consumption is an issue, not from the “green” standpoint but from the “is it really worth 250 MW to run one computer” standpoint.
  • IBM says that chips with carbon nanotube transistors will be available by 2020 and yield a 5x speed-up.
  • We in CFD often get trapped in certain ways of thinking, like how FEA is really mature, widely adopted, and robustly applied by non-experts. However, you can make the case that Mechanical FEA Is In Its Infancy with opportunities that sound very similar to those related to CFD.

Visualization Must-See

Because we in CFD rely heavily on numerical algorithms and visualization for our work, Mike Bostock’s work on Visualization Algorithms is a must-read. Not only is the work interesting, but its presentation on the web is fantastically visually pleasing. Take the time to read it.

Mesh For the Lady in Your Life

Gizmodo wants us to believe that the line of ladies’ handbags, purses, and clutches from designer Issey Miyake are inspired by origami but we at AFM know a mesh when we see one. Check out this animation of the Distortion clutch on Gizmodo.

The Bao Bao website defines their concept as “shapes made by chance.” This tells me that Issey Miyake knows more about mesh generation than we might first think. Because sometimes it feels like whether or not meshing works is a random act.

This delightful pastel Prism Rainbow bag from Bao Bao Issey Miyake is the perfect tote for any CFD conference.
