NASA
- Happy 75th birthday to NASA Ames Research Center. Who’s going to the open house on Saturday?
- Stability and Control CFD Investigations of a Generic 53 deg. Swept UCAV Configuration, from NASA Langley Research Center.
- Aviation Week continues to cover CFD. In this case it’s CFD for aeroacoustics from NASA Langley. Be sure to watch this related video.
Various
- Read about what’s new in ACIS R25. “Geometric quality is a never-ending task.”
- From PTC/Creo comes best practices for overcoming CAD challenges and one of them is to simulate early and often.
- Wofram introduced Tweet-a-Program. If you tweet a Wolfram Language program to @WolframTaP it will reply with the answer. [I don't know their language well enough to do anything interesting, otherwise I'd show you an example.]
- FEA for All also makes the case for reducing design cost via simulation.
- And let’s take it back to the beginning with RGBSI’s What is CFD?
- 4RealSim is looking for an application engineering who would be “delighted to work on a daily base with FEA and/or CFD.”
From Plastics Today comes this article about resolving boundary layers for mold filling simulations with Moldex3D. Click image for article.
Computers and Computing
- Between mobile devices and the cloud you can argue that most everyone is walking around with a supercomputer in their hand. Because of that, two things become important in this age of pervasive supercomputing: a fundamental understanding of computational principles and sufficient network capacity.
- On a related topic, COMSOL provides an intro to parallel computing.
- Here are six myths of high performance computing: Part 1 and Part 2.
- Ribbonfarm manages to weave together a tale involving flow pacing (the manner of injecting chemicals during water treatment), software delivery (the “UX of time”), and an original piece of music in The Rhythms of Information. [And don't forget to listen to the music.]
- Autodesk plans to convert all customers to subscription licensing over the next couple of years. Two notable factoids from the article are 1) the subscription model gets all customers on the most recent versions as opposed to perpetual licensees who are several versions behind and 2) for their entry level products the subscription model represents a 30% increase in revenue over current licensing.
- “Ultimately, it is likely that much more engineering design and computation will occur in the cloud.” True?
- More news on the quantum computing front.
- DNS of Turbulent Flows with Parallel Algorithms for Various Computing Architectures

Visualization
- Tecplot 360 EX 2014 Release 2 is now available.
- Intelligent Light news
- The beta program for FieldView 15 will begin soon, giving you early access to features like an improved OpenFOAM reader and a new “open licensed” tool for viewing XDB files.
- At the recent VINAS Users Conference in Japan, IL shared their thoughts on CFD postprocessing in the automotive industry. The slides are available for download at the link.
- At the recent HPC User Forum, IL presented their work on cloud computing for tera-scale CFD.
- IL added to VisIt the ability to write FieldView XDB files.
- Here’s the best of the visualization web for August 2014.
- CEI added new palette editing options to EnSight.
News From the International Meshing Roundtable
A poster illustrating CD-adapco’s winning entry for the IMR’s Meshing Contest. This year’s geometry was London’s Tower Bridge.
- Winner of the Meshing Maestro was CD-adapco with the entry shown above.
- Winner of the Meshing Contest (contest geometry = London’s Tower Bridge) was INRIA.
- Best technical paper was Sieger et al “Constrained Space Deformation for Design Optimization”
- Best technical poster was Ruiz-Girones et al “Optimizing mesh distortion by hierarchical iteration relocation of the nodes on the CAD entities”
- This year’s IMR Fellow is Paul-Louis George.
- Next year’s IMR will be in Austin, Texas. [Yee haw, just a couple hours drive south.]
Thanks to @zaidedan for live tweeting the event from which many of theses news items were gleaned.

Hand Knitted Mesh
Artist Alyson Shotz was a recent guest on The Modern Art Notes podcast and I really need to find the time to listen to her episode, especially after being greeted by this image when visiting her website.
The home page of Alyson Shotz’ website.
The image above seems to be a computer model of her piece Untitled, 2013 made from hand-dyed yarn and pins on wall from an exhibition at the Museum of Contemporary Art in Denver.

P.S. I feel compelled to apologize for the “hot mess” that his post is. Next week might not be any better and there will not be a post on Halloween because we’ll all be basking in post user group meeting glory and beginning a weekend celebration of Pointwise’s 20th anniversary.
