During the past week we’ve seen plenty of CFD articles themed around Valentine’s Day, the Super Bowl, and the Olympics. A few are included herein. This week’s cornucopia of CFD news fills the holiday void (until Easter) with plenty of CFD jobs, events, a few software releases, and a very elegant description of a computational geometry algorithm. The image shown here is from a CFD simulation of blood flow in the heart including details of the heart’s leaflet valves done by Waseda and Rice Universities.

CFD for…

• Aerodynamics of bobsleds from Airflow Sciences president Rob Mudry.
• CFD for reducing drag on a racing sailboat by 3D printing various components of the hull with a surface modeled after fish scales.
• CFD for owl tails and drones. (Registration required to read this article from New Scientist.)
• CFD for the heart.
• CFD for floating pipe.
• CFD for a Ferrari that’s being transformed into a Le Mans racer.

Who’s Hiring

• Cadence is hiring a senior CFD applications engineer in Fort Worth to generate meshes and run CFD solvers.
• Flow Science is hiring a CFD engineer.
• VICUS DT in Spain seeks a CFD engineer for marine applications.
• ENGYS has an opening for an automotive CFD engineer.
• Cadence has ten open positions in Brussels for software engineers, product engineers, and other roles.

News

• It appears that the folks at Dassault Systemes had a good 2021. Q4 software revenue was up 12% and total year software revenue was up 10%.
• Altair announced their acquisition of cloud-based PLM provider Cassini.
• Beta CAE released v21.1.6 of their software suite.
• GridPro v8.1 was released.

Events

• The International Conference on Numerical Methods in Multiphase Flows will be held in Venice on 28-30 September 2022. The call for papers is open with a due date of 15 March.
• The 33rd Parallel CFD International Conference will be held in Italy on 25-27 May 2022. Abstracts are due 27 February.
• You have until 18 March to submit your abstract for CadenceLIVE Silicon Valley on 8-9 June 2022.
• The SIAM International Meshing Roundtable (online) is happening next week and you can probably still register for free.
• This analysis of attendance at virtual conferences showed some huge increases in the diversity of the attendees versus in-person conferences: an increase of 250% for females and a 700% increase in “gender queer” attendees. The causation behind this correlation is key.

More News

• For those of you like math and applied geometry, the video A Strange But Elegant Approach To A Surprisingly Hard Problem (GJK Algorithm) answers the question “Do two shapes intersect?” and does so in a very precise and easy to understand manner.
• Just a reminder that the OpenFOAM User Guide is available online from CFD Direct.
• Here’s Visualizing Data’s best of the visualization web for October 2021.

Unifying Geometry

Artist Carmen Herrera recently passed away at the age of 106. As you can guess from Amarillo “Uno” below, she specialized in hard-edged geometric abstraction. It’s good that she lived so long because she didn’t really start to be recognized until very late in life. “I was liberated by being ignored,” she said.

So what’s the tie-in to meshing? When I first saw Amarillo “Uno” my immediate reaction was being zoomed in on a gap in a geometry model between two surfaces, one above and one below. Even the painting’s name “Uno” implies that we’re looking at a unified whole despite the gap; she’s making the painting watertight.
