This Week in CFD

Nalu-BladeResolved-DOEWith two weeks of CFD news to report, there’s more of everything from jobs to events, software releases, and cool applications. The wind turbine simulation here is from a new open-source CFD code called Nalu-Wind. Siemens released Screenplay, a cool looking tool for creating animations of your CFD results. And several articles describe the use of GPUs to accelerate CFD. After a long wait, our friends at Symscape are back with news. So let’s not prolong your wait – on with This Week in CFD.

  • Cray (now part of HP Enterprise) recently added to their trophy case at the American Business Awards.
  • Pointwise is now a sponsor of Revolution in Simulation.
  • For more on Rev-Sim, see this series of articles from Machine Design.
  • Congratulations to our friends at ITI (known for CADfix and a lot of other tech) for being acquired by Wipro for an estimated $45 million.
  • CFD Direct summarizes their fourth year of work on OpenFOAM.
  • Is ANSYS’ future bright?¬†No doubt yes. [Is simulation a religion? God no. I thought casting it as an art was bad enough. This idea of a simulation priesthood has to be exorcised. Religious puns intentional.]

We’re not in Kansas anymore.

Spencer Finch’s Back to Kansas has deconstructed the sunflower state (or at least its fictional depiction in The Wizard of Oz) and dropped it into an outdoor exhibition in Arkansas.

Imagine encountering this work while strolling through the northwestern Arkansas grounds of the Crystal Bridges Museum as part of their wonderfully named Color Field exhibit. It would be quite arresting, the juxtaposition of the organic with the grid, the contrast of natural colors with those from a hyper-colorized film, the displacement of a fictional place to a real one. I can only imagine how this looks in natural light, the flatness of the image plane with the rich depth of the forest.

From a bio of the artist on Artspace, Finch’s “works operate in the gap between the objectivity of scientific data and the subjectivity of creative expression.”
