Tesla Cybertruck Aerodynamics
I am not going to share my negative opinion on visual aspects of design of this vehicle (although I could be very verbose) but there are some technical issues I…

Serial Tool v2
Serial Tool v2 released! Awesome new features that every developer need while interfacing with serial communication.
Points and Vectors
I occasionaly write scripts for geometry optimization, therefore I have to wrestle with geometry. Graphically very easy problems become Ye Royale Paine In Ye Buttocks to solve analytically. At first…
SALOME for multiregion meshing
Context If you’re creating a multiregion mesh and you found this article you probably already know what SALOME , OpenFOAM, snappyHexMesh and chtMultiRegionFoam mean. In case you dont’ here’s a…
Truck Aerodynamics
Practical Background Our intuition will tell us that sharp or rounded objects will cause less drag when moving through fluid. Slightly less intuitive is the fact that changing the rear…
Listen to the flow
An unsteady flow has, by definition, fluctuations in velocity and pressure. More often than not this results in a more or less pleasant noise. If you fear this noise could…
Whistle Science
In a random conversation I recently had, a question popped up: why do whistles whistle? I had no choice but to reach for the most complex tool available: OpenFOAM .…
Arduino settings menu: updated
The dl-menu library, a simple one-level menu for 16×2 displays on Arduino, has been heavily updated: Text menu item There’s a new menu item for saving texts. Every character is…
