This Week in CFD

alon-7Plenty of new software releases this week including instantaneous CFD in Creo Simulation Live, part of the recently launched Creo 7. Then there’s an application of CFD to how tuna use their finlets to wander around. And you may have heard of Folding@home but what you haven’t heard is that there’s now an Another Fine Mesh team you can join in F@H. Shown here is a flame simulation computed using FDS from an article about designing hydrogenation reactors.

Folding at Home While Working From Home

  • No, I’m not talking about doing the laundry when you should be working.
  • Folding@home (aka F@H) is a “distributed computing project for simulating protein dynamics.”
  • The noises you hear in the background are my laptop’s fans furiously trying to dissipate heat while F@H does its thing.
  • Alert – and persistent – reader Dominic believes that while we’re all WFH we should put our underused computing resources (like those machines back at the office) and F@H to work on developing cures for viral infections.
  • According to PC Gamer [where I go to get all my computational chemistry information], F@H is running at over an exaflop.
  • Monica Schnitger is a f@n of F@H [See what I did there?]. And explains why I probably shouldn’t be running it on my laptop.
  • Ars Technica wrote about it.
  • Microsoft let’s F@H run in Windows 10’s sandbox.
  • Dominic suggested we form a team to see how high up the leaderboard we can go. So now there’s an Another Fine Mesh team, #262546. You’re welcome to join.
  • I’m old enough that I remember running SETI@Home.
  • Unclear whether this is modeling or simulation. [jk]

Meshing on Stamps

Sculptor Ruth Asawa will be honored by the U.S. Postal Service with a series of ten postage stamps featuring her wire mesh sculptures. Originally seen on Colossal, of these objects she said that the forms are both visible and invisible (transparent) such that the true object is only revealed by its shadow.

You can learn more about Asawa on her website, especially her drawings, paintings, and prints.

Bonus: Remember when a Gridgen grid was on a postage stamp?

    Our group ran that x15 cfd! 2 of the guys actually went up to DC to measure some parts of the plane in the Air and Space Museum – they went up in a lift and did their measuring!

      Tom, I remember when Bill Jones told us about the stamp and we were flabbergasted. We have a nice framed stamp and signed program from the unveiling hanging in our office. I was even invited to speak at a stamp collecting convention in Dallas to give the backstory.
