This Week in CFD

Mistakes and Failure

  • ENGINEERING.com shares six of the most embarrassing simulation mistakes you can make [and I’m willing to be we’ve all done one of them at least once. For example, #3 mixing SI and Imperial units.]
  • And in the same vein we read ten steps to successfully fail at CFD. #3 Never do CFD with small meshes. [This is a nice segue to…]
  • Read about mesh settings for FEA in Autodesk Simulation. [Who can resist a blog post series called “Sim with Jim”?]
  • Altair Hyperworks has been updated for aerospace applications by improving model-building workflows.

Computing

  • Simit is a new programming language that can speed-up simulations by a factor of 200 by coupling the graphical and matrix definitions of a system.
  • And when it comes to exascale computing, do we collectively know how to measure it and relative to what? This video lecture on exascale’s goals and baseline is worth watching. [“The beginning of wisdom is the definition of terms.” -Socrates]

In Other News…

  • ANSYS is getting a new CEO: Dr. Ajei Gopal will replace Jim Cashman on 01/01/2017, as reported by Monica Schnitger.
  • CPFD Software (makers of Barracuda) has formed a technical advisory board.
  • Aviation Week and AIAA are seeking nominations for their 2017 20 Twenties awards to recognize “top university talent” (i.e. twenty twenty-something students who are on track to be future leaders in aerospace.
  • And while we’re talking aircraft, will plasma wings truly change air travel?
  • And while we’re talking boats, will a stern hydrofoil truly change shipping?

Grids Light Up The World

Just so you don’t think I’m all talk (or text as the case might be) when it comes to this “mesh art” stuff, here’s a photo of a new toy I bought that is another example of meshes IRL. This is a 3D Illusion LED Lamp called “Space.” It’s only one of many meshed designs available from an online store I just happened to run across – Touch of Modern. This lamp has several different mode settings that make it change colors.

"Space," one of the 3D Illusion Lamps available at Touch of Modern. See link above.

Note: I have no affiliation with Touch of Modern whatsoever and received no compensation of any kind for mentioning their products and website.

BONUS: You have until 30 September 2016 to enter Science Magazine’s Dance Your PhD contest. I don’t know what’s more disturbing – the dancing or the fact that this year’s contest is the 9th annual.
