This Week in CFD

This week’s CFD news includes articles that pose questions about open source software. Does it have a people problem? And are people prejudiced against it? Proving that good things never get old, there’s a multi-part video series on fluid mechanics that’s as relevant today as it was in the 1960s. And if you’re looking for geometry models to 3D print, the new kid on the block is Thangs. The image shown here is a polariscope image of anisotropy in glass from an article about use of CFD to study the tempering of glass using ANSYS and OpenFOAM.

Reading, Listening, & Watching

Have you heard about Thangs? It’s a “Google for the 3D world.” [At least it’s not another “Uber for X.”] It helps you find 3D models, presumably for 3D printing. So what’s the first thing I do? Download the model above and mesh it with a simple anisotropic quad-dominant mesh. [This faceted geometry model was imported from its STL file into Pointwise and told to split itself based on a feature angle of 20 degrees. After setting one mesh edge length parameter, it was one button click to get the surface mesh, a second button click to assemble the volume mesh, and a third button click to generate the volume mesh. It took more clicks to make the picture look nice.]

From Pointwise

  • Here’s a video showing how you can use Tecplot to create a sizing field in order to generate an adapted mesh in Pointwise.
  • And in this video from the SU2 Conference you’ll learn how Pointwise’s flexibility and automation features were used as part of a framework for adjoint-based optimization of boilers.
  • This case study describes how the ability to generate and combine different types of meshes to accommodate complex geometry contributed to accurate CFD for rod bundles.

Geometric Space

How much of contemporary, geometric, abstract painting is influenced by the digital worlds of our computer screens? In the case of Torben Giehler, we’re seeing more AEC and GIS than discretization. He has created worlds or at least rooms that seem somewhat explorable despite being only 2D.

Maybe we should be asking how our computer screens can be influenced by abstract painting.
