This Week in CFD

Posted on October 21, 2022 by John Chawner

Thirty-four days until Thanksgiving. Sixty-five until Xmas. Seventy-one until 2022 is over. But only one day until the weekend. Let’s celebrate small victories with big news from the wonderful world of CFD. We have some tips on writing technical papers and a 2,000+ page paper on math for machine learning. Lots of event news including next year’s CadenceLIVE and this December’s HiFiLeD. Plus quantum computing, CFD applications, and more. Shown here is an image from work by Laizet et al on simulations of turbulent flow with moving objects on a moving mesh. (Coincidentally, Dr. Laizet is one of the keynote speakers at December’s HiFiLeD.)

This Week in CFD

Posted on October 14, 2022 by John Chawner

There’s something for everyone in today’s muster of CFD news. There’s a CFD contest for grad students, vibrating cars, updates from the SIAM International Meshing Roundtable, a report on progress toward the CFD Vision 2030 during 2021, and plenty of events including two turbomachinery webinars from us at Cadence. Pop quiz: What is the CFD simulation shown here? a) grilling a hamburger, 2) a dangerous chemistry experiment, III) me opening the door to the weekend, or D) other? Read on for the answer.

This Week in CFD

Posted on October 7, 2022 by John Chawner

Something weekend this way comes (credit @etherbrian). And with the weekend you get a side order of CFD notions. After a long wait, the AIAA’s CFD Vision 2030 integration committee published their report describing progress toward the vision during 2021. There’s a fascinating video of an LES simulation of a complete turbofan engine along with the accompanying technical paper (from 2020). And you’ll have to read to the bottom of this week’s post to figure out what this image is showing.

This Week in CFD

Posted on September 23, 2022 by John Chawner

Let’s get Navier-Stoked because it’s Friday and time to review recent news from the world of computational fluid dynamics. I want to draw your attention to a few specific articles beginning with the importance of stupidity. In case you couldn’t join us on the island of Maui for the 11th International Conference on CFD [humble brag], the proceedings are now online and will provide a weekend’s worth of reading. Also be certain to spend time with misconceptions about FEM and Jack Dongarra’s keynote on HPC. Shown here is a computational electromagnetics simulation of a B-1 aircraft performed on a Gridgen mesh from way back in the day.

Webinar: Making the Shipping Sector Greener by Leveraging CFD

Posted on September 21, 2022 by John Chawner

The times of drawing ships by hand are over as CAD vessel designs become more complex to reduce fuel emissions. Though maritime transport is one of the most energy-efficient modes of transportation, it is also a large and growing source of greenhouse gas emissions – 1,076 million tons of CO2, which is ~2.9% of global emissions caused by human activities.
