This Week in CFD

tenzor-les-rotor-IBM-technionThis week features updates on many CFD-related events and a deep article on predicting where CFD will be in 2030.  The image to the right is from that article on the TENZOR blog and shows an LES simulation using an immersed boundary method. And Talking CFD is back!

News & Reading

  • Do you know a student poised to change the face of the aerospace and defense industry? Nominations are now being accepted through 30 September 2018 for Aviation Week’s 20 Twenties, offered in association with the AIAA.
  • If you like articles that are rich with detail, you should read Predictions for CFD in 2030 which delves into RANS, LES, DNS, and other acronyms with which I was not familiar. As for meshing, the authors cite immersed boundary methods, mesh adaptation, and high order techniques.
  • Siemens Industry Software seeks a CFD engineer for a Technical Marketing position. [If this meshing thing doesn’t work out, this may be my fall-back job. Are you ready for that, Stephen?]
  • Season 3 of the Talking CFD podcast is ready to go with an initial episode launched on 25 April.

  • What do you do in Formula 1 when CFD correlates well with wind tunnel data but neither matches reality?
  • Here’s mention of CFD within the world of Australian supercars.
  • Within the world of Red Bull Air Racing [which you should try to go see if possible because it’s a blast], an Edge 540 aircraft was 3-D scanned and the resulting STL file converted into a geometry model in CAD to support CFD simulations. [Which makes me wonder where the original CAD model is.]

Meshes have such a broad visual appeal that they show up all over the place. Here is one on the home page of Clade, a new “private club for investors, philanthropists, and collectors to connect with their peers on a global scale.”


  • The ASSESS 2018 Congress will be held on 28-30 October near Atlanta. This event is one aspect of the ASSESS Initiative‘s goal of vastly increasing the availability and effectiveness of engineering simulation and brings together a broad spectrum of people in the industry to share ideas and promote advancement. This event is by invitation only as attendance is limited. Invitations can be requested here.
  • The Pointwise User Group Meeting 2018 will be held on 14-15 November in Fort Worth. The call for papers is open with a due date of 13 July. Attendee registration will open soon.
  • The Thermal & Fluids Analysis Workshop (TFAWS) will be held 20-24 August 2018 in Galveston, Texas. The call for papers is open with a due date of 25 May.
  • AIAA SciTech 2019 will be held 7-11 January in San Diego. Abstracts are due 11 June.
  • The Converge User Conference North America will be in Madison, Wisconsin on 24-28 September 2018.

When Worlds Collide

pwallI love it [am easily amused?] when two of my interests come together. So you can imagine my joy at seeing how Walt Disney World painted a mesh motif on their so-called Purple Wall, an oft-used meeting place that bridges Main Street USA and Tomorrowland.

I’ve reached out to some Disney folks to see if I can get any backstory on why and how this came to be. If and when I get an answer, I’ll share it here.

    The Disney mesh is tangled. It needs some smoothing!

    Tangled! Seeing your everything…
