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…
nRF24L01+ template
Few years ago, while Labyrinth Ljubljana hardware start being developed, small and cheap nRF24L01+ RF module was used for communication between control unit and battery powered flashlight.I found a great…
VS Code STM32 IDE + Keil project
Problem Few years ago I started with Keil + STM32 dev boards. Than STM32CubeMX was released and I started using it, generating Keil project as output. This was good enough for…
Parallel ParaView
Using OpenFOAM in parallel with MPI is well explained in the OpenFOAM manual. Rendering results in ParaView on multiple cores on a desktop computer is a little less explained on…
