- MUST READ: From our friends at ANSYS comes this story of how CFD was used to design a method of improving aircraft cabin air quality. Specifically, the study showed how to “effectively curb pathogen inhalation by up to 55 times and improve fresh air inhalation by more than 190%.” What makes this work even more amazing is the researcher’s age: Raymond Wang is only 17 years old.
- CFD was used in a study of vortex induced motion of semisubmersible offshore drilling platforms.
- And another [perhaps the same?] use of CFD for VIM. [But this one had a picture.]
- Here’s an interesting compilation of research from the Symposium on Computer Animation including several fluids-related topics.
- EnSight was used in a CAVE to visualize simulations of solar flares.
- Tecplot released Tecplot Chorus 2015 R2, their software product for interrogating and comparing multiple parametric CFD solutions simultaneously. This new release includes new capabilities for identifying design points that are edges of the parametric space and improved tools for managing thousands of simulations.
- CFD solver PyFR v1.0.0 was released.
- Also from the PyFR folks is this article about their use of GPUs.
- Software Cradle released SC/Tetra V12. [PDF]
- CRAFT Tech has written a Fluent UDF for flames – specifically the interaction of turbulence and chemistry in a flame – and guest blogged about it on ANSYS’ site.
- Aerosoft released GASP 5.2.1.
- Desktop Engineering wrote about the release of STAR-CCM+ v10.0.4.
- ArtMesh is a quad/quad-dominant surface mesher for Windows that’s free “for a long period of time” and uses OBJ files as the geometry definition.
News and Events
- ANSYS has a lot of job openings all over the world for software developers and application engineers.

Crossing a Line Somewhere for Somebody for Certain
Underwear model and CFD researcher named “world’s sexiest math’s teacher” is said to enjoy modeling “wet steam flow.” No cliche is left unused in this article.
All I have to say is:
- I hope this is not the start of a trend.
- I ask all the ladies to not objectify me and please respect me for my mind.
Mesh Art – Coincidence or Intent?
Nick Wyman, Pointwise’s director of applied research, was working on an unreleased version of our meshing software and pressed the wrong button. The result, shown below, was what he termed objet d’art.
Perhaps you’re thinking “Ha ha, that’s not art.” Well, consider the following. During last week’s AIAA Aviation conference in Dallas, Prof. Robert Haimes (MIT) and I spent an afternoon on an art appreciation tour around DFW and eventually found ourselves at the Dallas Museum of Art standing in front of Alan Saret’s Deep Forest Green Dispersion (see images below).
What can you say now about meshes and art, intent and coincidence?
