We are attuned to the fact that the law of nature, or nature’s rule, drives various scientific phenomena. Humans often replicate naturally occurring phenomena to achieve a desirable outcome, similar to how scientists mimic photosynthesis to generate…

If you're in the field of computational fluid dynamics testing or studies, you already know how much time and effort it takes to complete the tasks involved. Hours upon hours are spent on geometry clean-up, meshing, and post-processing. Furthermore,…

This article was first published in June 2012. It was so popular there it's reposted here to reach a broader audience.

“We know embarrassingly little about how the mesh affects the CFD solution,” said Prof. Carl Ollivier-Gooch of the University of…

The 2nd AIAA Geometry and Mesh Generation Workshop is taking the qualitative out of mesh resolution by adopting a quantitative definition that will evolve as we move toward the vision of CFD in the year 2030. 

When asked about the resolution of a mesh…

There’s an old joke in the CFD community: “Large eddy simulation is ten years away from being useful, just like it was in 1977.” Of course, that’s never been entirely true. Seventeen years ago, I did an LES analysis of a tiny wedge …

Unstructured meshing can be automated for much of the mesh generation process, saving significant engineering time and cost. However, controlling numerical errors resulting from the…

Hi, I’m Peter Weitzman, and I’m the president of Agile Engineering Software at Concepts NREC. I lead a team of software developers, application engineers, product managers, and salespeople who develop, sell and support specialized software for the design…

Hello, I’m Julio Mendez, a CFD Scientist currently working at Corrdesa and using CFD to study electrochemical applications.

My journey in CFD started in 2007 when I was looking for a topic for my undergraduate thesis at La Universidad del Zulia in…

Hi, I’m Joshua Strodtbeck, and I’m a Product Management Director at Cadence Design Systems and I do product management for Fidelity CFD. I first dipped my toes in industrial CFD at Rolls-Royce in 2006, when I did an LES simulation as an intern, and I…

Tip clearance flow is the flow that passes through the small clearance gaps between rotating and stationary components of a turbomachine. The size and shape of such gaps are directly…
