This Week in CFD

particle-in-cell-satIn this end-of-summer edition of This Week in CFD we see several outstanding examples of applied CFD including a heart valve done with STAR-CCM+, a tuna done with SC/Tetra, and certification by CFD using FUN3D. And then there’s this simulation of contamination around a satellite done by Particle in Cell for which yours truly made the mesh. (Even I can import a CAD file and press the “mesh” button.)

Love these images of geometry and overset mesh for simulation of a mechanical heart valve from the Simcenter Blog on how CFD in the form of STAR-CCM+ can help save lives. Images from siemens.com.

Alert reader Jim began his email with the humble brag “I just returned from the Alps…” where he found these mesh sculptures in Bettmeralp, Switzerland.

Alert reader Bernhard shared this image he found online of a quad-dominant, cut-cell mesh embedded within a Cartesian grid.

Triangle at Sunset

Let’s get this out of the way right up front. Maybe you could’ve done this yourself, but you didn’t. And it’s not what it may appear to be at first glance so you probably couldn’t. [Too defensive?]

Photographer Reuben Wu is working on a series of landscape photographs under the project name Aeroglyph in which the geometries are only made visible by photography. That’s because the glyphs are drawn by lighted drones and captured by long exposure. Regarding his work in general, Wu says “I am driven not just by the urge to create imagery, but by a desire to explore new places as if they were unknown territory.”

As first seen on Colossal.com, Wu’s work ticked many of my technical boxes: the triangular mesh cell, use of the words “aero” and “glyph” (Pointwise’s scripting language), and the use of drones. From an artistic standpoint, the addition of the geometry to the otherwise placid scenery activates the photograph by juxtaposition of the modern (the drones, the symbols) and the ancient (the mythology of constellations).

Bonus: I’m hoping my friends who are engaged in particle simulations will enjoy the film Volumes by Maxim Zhestkov.

P.S. Sorry for the length of this post but it’s two weeks of CFD news. Plus I feel I’m snarkier today than normal but it’s been a long week and I’m looking forward to the upcoming 3-day holiday weekend – so I can work more.

P.P.S. or P.S.S. I can never remember which one is correct. I feel as though I should categorize all of these posts as “Off Topic.”
