This week’s This Week includes the most eclectic set of CFD applications I can recall, from the usual race cars and rockets to teeth, noses, and dinosaur necks. (One of those eclectic applications is shown here: ventilation of a latrine using SimScale. I don’t even want to know what the red color represents.) In addition to the usual software releases the SU2 folks have created a foundation to help move their open-source code forward. And there’s a trio of meshing articles and a trio of job openings. We lead off with several Pointwise news items which isn’t our usual style but there are things we think you might want to know about.
News from Pointwise
- Today is the last day for our survey on Workstations for Meshing. You can help guide our software development efforts by taking six minutes (according to Survey Monkey) to tell us what workstations you’re using for meshing today and what computers you’d like to use for meshing tomorrow.
- Will you be attending AIAA Aviation in Dallas next month? We’ll be in the exhibit hall, presenting three technical papers, and hosting a reception Sunday night as an early celebration of Pointwise’s 25th anniversary. Hope to see you there.
- Summer in Texas is hot but our training courses will be even hotter.
- 16-18 July = Learn Pointwise from UI to plugins and everything in between
- 06-08 August = Automate meshing with templates and macros using Glyph scripting
- Read about how we’re evolving meshing in the case study The Evolution of Faster, Easier, and More Reliable Automated Meshing.
- A couple of recent blog articles have gotten some positive reviews so you might want to check them out.
- We continue our quest to add an engineer to our technical support team. See the link below.
- NASA’s space launch system (SLS) for the Europa Clipper. See image above. [To be fair, this article is mostly about the wind tunnel testing. Highly recommend you read this.]
- a SAE Formula Hybrid race car.
- propeller nozzles.
- Evaluation of needle movement effect on root canal irrigation. [I got woozy just reading the article.]
- NASCAR. About which driver Joey Logano says the “squiggly lines” give drivers a good view of what’s happening aerodynamically.
- You prefer driver Brad Keselowski? CFD has contributed to some rules changes coming from the fact “nighttime is the new daytime for NASCAR.”
- fireplace design.
- Plesiosaur necks. “hydrodynamic implications were not a limiting selective pressure on the evolution of long necks in plesiosaurs.”
- latrine optimization.
- a Porsche 964.
- deviated septum.
Grids and Meshes
- Our friends at GridPro describe how they generate structured grids for objects with a large number of cooling holes such as a turbine blade. See image above.
- How to choose your mesh size for FEA simulation. [Hint: Do a mesh convergence study as part of your V&V.]
- Oh, you want advice on choosing mesh size for CFD? Here’s some from LEAP Australia using ANSYS for a race car.
News, Events, & Jobs
- The winners of the SimScale Community Contest 2019 have been announced in AEC, aerospace, automotive, electronics, and valves & pumps. It was tough for me to pick a favorite but I like Anirudh Singh’s simulation of graphics card cooling. See image above.
- The 35th International CAE Conference and Exhibition will be in Vicenza, Italy on 28-29 October. [Pointwise will be a first-time exhibitor this year so come visit.]
- ASME Turbo Expo 2019 is in Phoenix this year on 17-21 June.
- Numeca seeks to hire a multiphysics CFD engineer.
- Oak Ridge National Lab has an opening for a computational scientist for large-scale simulations.
- Pointwise seeks a mesh- and CFD-loving engineer for our technical support team.
- Altair brought in $128 million during Q1, an increase of 13%.
- CAESES 4.4.2 was released.
- Fans of the open source CFD solver SU2 should sign up for the SU2 Foundation.
- Resurf v3.022, point cloud to NURBS software, was released.
- ENGYS released HELYX v3.1.2.
- COOLFluiD “(Computational Object-Oriented Libraries for Fluid Dynamics) is a component- based framework for scientific high-performance computing, CFD and multi-physics applications, originally developed at the von Karman Institute for Fluid Dynamics.”
Who knew? Famous for his architecture, Frank Lloyd Wright was involved in textile design. And facets. To see more, head to NYC’s Metropolitan Museum of Art for Frank Lloyd Wright Textiles: The Taliesin Line, 1955-60.
Sad Bonus: I was saddened to learn earlier this week that the Red Bull Air Race Championship will not be continued after the 2019 season which itself has been shortened by cancellation of the only U.S. event (Indianapolis, October). I’ve made no secret of the fact that ground-based motorsports don’t really get my engine running (sorry for the pun) but I loved the Red Bull Air Race. Enjoy this video on the raceplanes of the Red Bull Air Race.
