This Week in CFD

chorus-f1-exampleIt must be the season for CFD contests as ANSYS just opened submissions for their hall of fame, EDEM announced winners of their viz contest, and there’s still time to enter your mesh for Pointwise’s The Meshy. Maybe as a counter to our recent post about the Red Bull Air Race, Tecplot Chorus shares how it was used for Formula 1 racing (as shown here). And, did you hear that Pointwise is hiring?

My favorite winner from EDEM’s viz contest (see link below) is this simulation of a rotary soil tiller from the Univ. of South Australia. Image from


My favorite from ANSYS’ 2018 Hall of Fame: academic best-in-show winner FTGM for this aneurysm simulation. Image from See link above.


How expensive is it to be an engineer?

Does engineering really come with the highest amount of personal expenses of any job? That’s the conclusion of a study by CV-Library as reported by DEVELOP3D. Now I’m not picking on the reporting by DEVELOP3D but rather the conclusions of the study. Here are the top work-related expenses reported by the study’s participants.

  • Commuting. [Not a work-related expense, at least in the U.S. as per the IRS where it cannot be written off as a business expense.]
  • Lunch. [Not a work-related expense, IMO. You’d be eating lunch regardless of where you worked or whether you worked at all.]
  • Clothes/Uniform. [I interpret “clothes” as what you choose to wear to work and “uniform” as what you’re required to wear to work. The latter is a business expense, the former is not.]
  • Morning coffee. [Gimme a break. No way.]
  • Workplace snacks. [In general, I agree it’d be nice if your workplace would provide food and drink throughout the day.]

Given  what I’ve seen here in the U.S., public school teachers at the elementary and secondary levels may have the highest level of actual work-related expenses they pay out of their own pockets to outfit their classrooms.

Maybe a better measure of this study would be the ratio of personally-paid, work-related expenses [assuming we could agree on a definition of what qualified] to average or median salary in that profession.

I really don’t think this article will garner any sympathy from folks outside engineering.

And while we’re on the topic, aerospace engineering is the 6th highest paid branch of engineering as per this article from GrabCAD on the 10 highest paying engineering degrees.

  • CFD was used to design a magmeter.
  • Here’s an application of machine learning to CFD.
  • Machine learning and CFD show up together again in this announcement of a partnership between McLaren Racing and King Abdullah University of Science and Technology.
  • Applied CCM has an opening for a CFD Modeller in Melbourne, Australia.
  • Intel is working on an exascale chip called a dataflow engine that would do away with X86. [I lack the computer expertise to understand exactly what this means.]

Forget Polyhedra: Curvahedra

From the “I wish I had thought of that” category comes Curvahedra, “the next generation of puzzle.”

More to follow.

Bonus: Congratulations to “scientist, artist, programmer” Mark J. Stock for having his hour-long video Mixing Simulation #155 chosen as one of the pieces curated by Boston Cyberarts for the lobby of the office tower at 100 Federal Street in Boston.

Alert reader Carolyn pointed out that I had forgotten to include a reminder about the 2nd AIAA Geometry and Mesh Generation Workshop so I updated this post after its initial publication.
