This Week in CFD

News

  • Intelligent Light won a 2nd HPC Innovators Award from IDC for their work on analyzing large CFD datasets. The award was presented at SC13, the supercomputing conference. A webinar on 22 January with Intelligent Light and Cray will describe the technology behind this achievement.
  • If you’re one of those jaundiced people who believe that CFD stands for Colorful Fluid Dynamics, this CFD code is for you: an ASCII based implementation of the smoothed particle hydrodynamics method. [As a fan of ASCII art back in the day I found this to be pretty darn cool.]

  • Dassault Systemes acquired 3D visualization software firm Realtime Technology.
  • Altair acquired electromagnetics software firm EMSS.
  • Exa reported a 12% growth in income for 2013 Q3 relative to the same period last year. Included in that $14.1 million total is an 8% growth in license income and a 30% growth in project revenue.

FYFD’s Insight into Social Media and Fluid Dynamics Outreach

During November’s APS Division of Fluid Dynamics Meeting, Nicole Sharp presented some findings obtained from surveying the readers of her fluid dynamics blog, F%^$ Yeah Fluid Dynamics.

  • The blog has 180,000 followers and nearly 14,000 unique visitors per month.
  • Roughly half the readers are in the 20-29 age range.
  • Even though interesting photographs attract readers, it’s the explanation of various phenomena that keep them coming back.
  • 29% of readers have been positively influenced by FYFD to pursue fluid dynamics in their schooling or career.

Because FYFD’s audience desires even more content (more frequent, longer, more original posts) the question Nicole poses to the community is how to best meet those desires in a way that benefits the field of fluid dynamics.

Meshing the Ocean

I had heard that researchers simulating oceanographic flows preferred Cartesian grids but this is taking it a bit too far. The photograph below shows a phenomena called a cross sea state in which two systems of waves intersect at oblique (and in this case, right) angles.

    I have to admit, at times I’m one of those “jaundiced” people, so I’ve got to check that program out!

    I’m not really sure what jaundiced means in this context, but it doesn’t sound good. It sounds like I need to go see a doctor! :)

    BTW John (and everyone at Pointwise), thanks for doing all you do for CFD.

    You’re welcome, Martin. Let us know how the ASCII CFD program works out.

    If you generate any interesting images of your results let me know and I can post them.
