Software

  • [At the risk of being a jerk], the article 7 Challenges CFD Engineers Face and How They Can be Solved with the Use of Simulation Tools leaves me scratching my head. For example, #3 is Presenting Data to a Non-Technical Audience – which truly is a challenge – mentions “appealing display” and “colours [sic] or contours.” I’ll propose that non-technical consumers of simulation results need to receive data in the same form as any other engineering data; presented as performance maps in the vernacular of the application domain. [Every time this issue comes up I’m reminded of the “machine that goes ping.”]
  • How does cloud-based software address the issues of crashes and data loss? [Can’t we address this on the desktop too?]
  • Beta CAE announced the release of v16.2.1 of their software suite.
  • Frustrum announced the beta of the new Generate software that promises to integrate design and topology optimization.
  • Looking for free, open source, 3D CAD? 3D CAD World lists several options for you.

Structured and Unstructured Art

Serendipity led me to London’s Jessica Carlisle gallery where I found artists exploring both structured and unstructured grid motifs.

Vera Boele-Keimer explores (dis)order, and searches for a balance between stability and fragility – as though she’s generated structured grids before.

Katrina Blannin, on the other hand, goes for the unstructured mesh motif through works that are rule-based (Delaunay?) yet allow her to explore tonal variations that produce visual rhythms. The work shown below looks like it could be a screen shot from Pointwise.

Bonus: Alert reader Tessa Uroic found the structured grid below IRL in Porto, Portugal.

    I know it’s uncool to be the first to comment on your own blog post but…

    Two people have pointed out to me that “colour” is the correct British/Canadian way to spell the word us Yanks spell as “color” and therefore my inclusion of “[sic]” (from the Latin sic erat scriptum meaning “intentionally so written”) was erroneous.

    My sense of humor (humour?) is sometimes too dry. My inclusion of “[sic]” was meant as a playful needling of our friends across the pond (pound?).

    Vive la difference! (From the French meaning “Never make fun of my writing.”)
