This Week in CFD

And we have reached the end of year and the last issue of This Week in CFD for 2021. Many things have changed over the last twelve months and I’m not referring to the pandemic. In April, Pointwise was acquired by Cadence Design Systems and joined the former Numeca team (acquired a couple of months before us) to create the Cadence CFD team. This has given all of us a great opportunity to make new friends and begin new collaborations. Imagine the possibilities by bringing together the geometry modeling and mesh generation experience from both Pointwise and Numeca in a way that elevates both products. But maybe that’s all a bit too myopic, focusing just on what happened to us. CFD is such a vibrant community and hopefully you’ve seen that by what we’ve shared here. This week’s news clears most of my backlog of bookmarks so that we can start fresh in 2022.

Have you heard about Everything for Engineering? It’s an “ecosystem is connecting the world of Engineering Industries, Engineering professionals & Engineering Students to provide an opportunity to Share, Learn & Earn.”

Thangs Workspace (beta) is a “GitHub for 3D models.”

What do we say? I’m a sucker for a cool mesh pic. This one’s from the announcement of Polygonica 3.1 for “polygon mesh modeling.” Image from

This appears to be an archive of every CFD article from Siemens Simcenter.

Formula SAE is a great opportunity for students to gain experience with simulation (among other things). The Leap CFD blog profiles use of ANSYS’ simulation products by the Edith Cowan University Racing team.

I had a friend in high school who could solve all the brain teasers in the Tau Beta Pi magazine without breaking a sweat. I can’t solve them to this day. So someone else is going to have to grok Pick’s Theorem for me. It says that given a polygon defined by planar lattice points, its area is a function of the number of boundary and interior points.

Beyond PLM delves at length into How PLM Will Expand Into Electronics and Semiconductor Design.

Polygons make any image better. Triangula is available on GitHub.

Tim Kruger provides a video Introduction to the Lattice Boltmann Method.

CFD for upgrading your Honda.

As I hope you know, AIAA SciTech (3-7 January, San Diego and online) is coming up soon and several members of the Cadence CFD team will be on the ground in San Diego attending technical sessions and workshops and meeting all our CFD friends after a long conference hiatus. Unfortunately, out of an abundance of caution regarding the Covid-19 situation, we will not have a booth in the exhibit hall nor will we be hosting a reception as originally planned.

I don’t normally find CFD-related news in Harvard Business Review but here it is: How Cloud-Based Supercomputing is Changing R&D.

Here’s Visualizing Data’s best of the visualization web for July 2021 and August 2021 and September 2021.

The 2021 Year in Review issue of AIAA’s Aerospace America magazine is now available. This issue is always my annual favorite and the only one I keep (the print version). You can browse how all the technical committees view progress in their respective areas of expertise including the CFD Vision 2030 integration committee.

Gotta love what GibbonCode (an open source Matlab toolbox) is doing for geometry processing for bio applications.

The 3rd preCICE Workshop will be held virtually on 21-24 February 2022. Call for prerecorded presentations is open until 17 January. In case you’ve forgotten, preCICE is “The coupling library for partitioned multi-physics simulations.”

Just a reminder that this year’s International Meshing Roundtable (of which Cadence is a proud sponsor) will be 100% online.

For those of you with trouble sleeping, I was interviewed by Revolution in Simulation (an organization of which Cadence is a proud member).

Join on 25 January for the live online course New Features in Pointwise V18.5. The course will cover some of the coolest new features and by that I mean the Flashpoint automation suite including the new Automatic Volume Meshing and updated Automatic Surface Meshing. Registration is now open.

Originally seen in Aviation Week but because that’s behind a firewall, here’s another link to Prof. Martins’ views on how multidisciplinary design optimization can lead to innovation and cost reduction in aerospace engineering.

The ASME Turbo Expo will be in Rotterdam on 13-17 June 2022.

Years after it was created, this remains my favorite mesh image. Created in the old Gridgen software by my longtime friend, colleague, and alert reader Erick, it’s a nice way to sign off for the year. This Week in CFD should return sometime in January.

Best wishes to everyone.
