Applications
- Boeing’s CFD software helped Callaway Golf produce a tournament winning driver.
- CFD software for designing sailboats.
- Do you think like a simulation engineer? Read about six rules for focusing your thinking.
- Here’s a very cool article about shrink-wrapping and meshing an aorta with geometry from an STL file using ANSYS. Don’t skip the video. (See image below).
- Univa’s Grid Engine provides the HPC resource that powers CFD for Formula-1.
- Read about varying the shape of a fuel injector in CAESES.

Computing
- Remember last summer’s announcement of the National Strategic Computing Initiative, the presidential directive aimed at exascale computing? A discussion about NSCI – or more accurately the lack of apparent progress on it – at the recent HPC User Forum began with a “It’s all BS.” and included commentary on the issue of what NCSI success would look like. See also the discussion of the “ISV problem.”
- On a related note, the report The Vital Importance of High-Performance Computing to U.S. Competitiveness advocates for NSCI.

- Tecplot 360 EX 2016 Release 2 includes updated data loaders and support for the 3D SpaceMouse.
- Convergent Science is making good use of Polygonica’s geometry libraries.
- Beta CAE released v16.1.2 (a maintenance release) of their software suite.
- Part 4 of a series on meshing in SolidWorks Flow Simulation.
- Applied CCM released Caelus v6.04. This fork of OpenFOAM includes many new interpolation schemes and a publicly available source code repository for collaboration.
- I don’t recall ever seeing a video trailer for CFD software before, but here’s one for the upcoming release of SolidWorks Flow Simulation.
- The Linux version of meshCurve (for elevating the polynomial degree of meshes) is now available.

Quizzes, Contests, Surveys, and Awards

- It’s amazing what you can 3D print these days as exemplified by Nick Ervinck’s sculpture Wolfram, produced on the new Stratasys J750 with support for 360,000 colors as reported by DEVELOP3D.
- Speaking of 3D printing, Stratasys and Desktop Engineering are offering a prize of $1,000 for one participant in their 3D printing quiz.
- Speaking of quizes and surveys, Lifecycle Insights is conducting their 2016 Simulation and Analysis Study focusing on practices and technologies used for simulation. [I strongly recommend all users of simulation share their thoughts and participate in this survey.]
- KOMPAS-3D users will want to participate in Ascon’s 3D Modeling Contest.
- Kitware was recognized as a Top Workplace.
Grab Bag
I just really like this image from an Actran acoustic simulation. Image from MSC. Click image for article.
- MSC has been writing a lot lately about acoustic simulations (see image above) and this article caught my eye: Tuning Acoustic Qualities of Audio Devices with Simulation. Years ago when shopping for stereo speakers [consult your parents for an explanation], I learned that a significant amount of audible distortion comes from vibration of the casing. [Ended up buying a pair of Celestion SL-6s.]
- “Licensing models must change” was a refrain from the original ASSESS Summit. But how? And why? WorldCAD Access summarizes the positions of CAD vendors and subscription based licensing. [Subscriptions here mean annual licenses as opposed to perpetuals. What about monthly subscriptions?]
- Autodesk: Everyone wants subscriptions.
- PTC: 70% of users want subscriptions.
- Dassault: No one wants subscriptions.
- On a related note, read about ANSYS’ pay-per-use licensing.
- FluiDyna, an Altair partner, obtained elite status with NVIDIA for their GPU-accelerated CFD.
- The Siemens Simulation Symposium 2016 will be held 13-14 September in Troy, Michigan.
- The 20th International Association for Mathematics and Computers in Simulation World Congress (IMACS 2016) will be held in Xiamen, China on 10-14 December 2016.
- The ISGG Symposium on Numerical Grid Generation will be held at IMACS 2016.
- Here’s a nice summary from COFES of CAD translation and formats.
- Have you been listening? Nine episodes of the Talking CFD podcast are now online.
Whale of a Winner
I think you’ll agree that UVA student Yan Ren’s visualization of killer whale kinematics and wake is a worthy winner of Tecplot’s 2016 Plot Contest.

Bonus: MIT students make a sculpture out of water.
P.S. I hope you like this “husky” version of This Week in CFD because we’re going to skip next week and publish next on 13 May. And there’s something else interesting on the calendar for that day – besides being Friday the 13th – that we’ll say more about later.
