The past two weeks have yielded two “must see” CFD articles. The first is on the data management and visualization aspects of using pressure sensitive paint in wind tunnel testing of NASA’s Space Launch System. The second delves into splines which are so essential to geometry modeling and meshing. There’s lots of other news too, including the anouncement of Altair’s acquisition of DEM Solutions. The image shown here is a screen capture from a video about the acquisition showing one application of EDEM.
- Sometimes fluid dynamics pops up in unexpected places. For example, printer company Oce has an entire webpage dedicated to fluid dynamics.
- In case you missed it, Siemens is offering (registration required) a white paper from Tech-Clarity on Addressing the Bottlenecks of Simulation. In this report we read that 38% of simulation time is spent on preprocessing and of that 38% two-thirds is geometry model cleanup and meshing.
- CFD firm WindSim will strategically partner with Shanghai Electric Wind Power Group for the development of new wind-power software.
- NUMECA and coupledNumerics announced a joint venture to further develop and commercialize the latter’s pressure-based flow solver. [Two observations. First, a joint venture seemed inevitable from their names alone. Second, the article mentions the “Energetics” industry, a term that’s new to me.]
- The OpenFOAM Foundation launched their funding drive for 2020.
- Altair has acquired DEM Solutions and their EDEM software for discrete element modeling and bulk materials simulation.
- Ducati’s Streetfighter motorcycle [described as “bonkers” which I assume is good]
- ship design.
- Ferrari’s 488 GT3 Evo “with over 18,000 hours of calculations and computational fluid dynamics.”
- SHARK’s Race-R Pro GP cycling helmet.
- 2021’s Formula 1.
- Chevy’s Camaro for 2020’s NASCAR.
- Mudguards. For bicycles.
- Nike’s Vapor swim goggles.
- Bloodhound‘s attempt at setting a landspeed record.
- Discovering the similarity between cracked windshields and kidney stones.
- ANSYS has an opening for a Senior Software Developer -Meshing in Pune, India.
- Medical technology company BD seeks a senior engineer for CFD work in North Carolina.
- The University of Alabama has an Assistant Professor opening with CFD as an area of interest.
AIAA CFD Workshops
- The 3rd AIAA Sonic Boom Prediction Worskshop will be held 4-5 January 2020 at SciTech.
- The 1st AIAA Transition Modeling and Prediction Workshop has been announced. It will be held on 13-14 June 2020, the weekend prior to AIAA Aviation in Reno, Nevada. Meshes for the benchmark case (NASA’s CRM natural laminar flow variant) should be available in January 2020 and your abstracts are due in February 2020.
- The AIAA Large Eddy Simulation Workshop on Smooth-Body Separation will be held in January 2021 in conjunction with AIAA SciTech in Nashville. The workshop organizers are currently seeking your intent to participate.
- Take a virtual 3D tour of NASA’s 8×6 supersonic wind tunnel.
- ParaView now supports something called an explicit structured grid for geophysical applications and I’m wondering why no one came up with this before.
- Siemens release Webapp Server 2019.2 for “democratizing access to system simulation models.”
- DEVELOP3D takes a look at the new KVS QuickSurface 1.0 for working with scan data including converting it into surfaces to be exported to a CAD system.
- These are the same folks that brough you Mesh2Surface for Rhino.
- Learn more about Screenplay, the animation capability for post-processing results from Simcenter STAR-CCM+ 2019.2.
- 3D-Tool CAD-Viewer and Converter Version 14 was released.
- Again, Siemens Digital released the latest updates to STAR-CCM+ including combustion modeling and more.
- When I think of turbulence, astrophyics and the formation of new stars is not what first comes to mind. Regardless, behold the world’s largest turbulent simulation EVAR (1 trillion grid elements, 45 million CPU hours, other large numbers).
- ENGYS released HELYX v3.2.0.
- Save the dates. The 11th International Conference on CFD will be held on the island of Maui on 13-17 July 2020. Abstracts are due 03 February 2020. [Did I mention it’s in Hawai’i?]
- Monica Schnitger shares some thoughts based on the recent Altair Technology Conference. “The world isn’t a single-physics problem, so we need a range of solvers to help us understand it. We don’t all have a 3D model to analyze, yet still need to make decisions, so tools that span from 0D/1D to 3D are essential. Not all firms have analysts; there is a place for designer-calibrated simulation tools in this market.” Read more here.
- Next year’s 3D Collaboration and Interoperability Congress (3DCIC) will be in Golden, Colorado on 12-16 October 2020.
- A wrap-up of the CAESES Users Meeting 2019 including downloads of all the presentations.
News from Pointwise
- We have a new case study from researchers at Auburn University about the use of CFD to evaluate truck platooning.
- We recently launched the freely-available Pointwise Viewer that you can use to visualize and measure virtually* any mesh.
- *There’s always a catch, right? Meshes must be of types compatible with Pointwise’s current data structures and for which a reader exists or can be written using Pointwise’s Grid Import Plugin SDK.
- Software is no-cost, registration is required.
- Free software is free like a puppy is free.
- If you prefer software you have to purchase a license for, we have a new, on-demand webinar about the new features in Pointwise V18.3 including hex-core meshing.
Enhancing Reality Through Meshing
Thank you to alert reader Andy for introducing me to digital artist Andy Walker (no relation). The latter Andy has an interest in the interplay of color and shapes and now uses “hand-drawn colored triangles” to “enhance the vibrancy and intensity of my original photographs.”
Read that again. The mesh enhances reality.
He’s “flooding the world with color, one triangle at a time.”
P.S. Today’s post was written under the heavy influence of DayQuil so all typos are the medicine’s fault.
