These are some notes on the components of the memory management system in OpenFOAM. I would expect to find these building blocks in any code that involves large chunks of data that you cannot possibly keep copying back and forth. The two components that OpenFOAM uses are variations of smart…

There’s no way around turbulence modelling. When George Box famously said “All turbulence models are wrong, some are useful”, I’m sure notice was taken as to how absolutely useless CFD results are for setups that lack appropriate turbulence models and mesh resolution near a wall. …

I spent a summer with a research group specializing in a variety of topics in non-linear dynamics, one of them being the Fluid Structure Interaction (FSI) of flapping wings. …

The previous articles in this series took on debugging the simpleFoam solver through a VSCode debugger. SIMPLEC, a “consistent” implementation of the SIMPLE algorithm can be toggled on and off via the “consistent” switch in your fvSolutions file. The theory on SIMPLEC is a bit dense — so let’s go…

Tip — This is not meant to be a standalone article. It’s much more useful walking along this like a tutorial and not just reading through . So I highly recommend catching up to the point of entry in this article with the previous one. Let’s look at the actual…

This is a the second article in a series exploring utilities of OpenFOAM for viewers beginning with CFD — geared towards OpenFOAM beginners. The toolbox has a steep learning curve, but a see-through box offers far more control than a black one. …

Well, if you’re this far, you’re no stranger to open source fluid simulation software. …
