Do i understand correctly the video from 1, wants to make a propulsion system out of a spinning rod to leverage the Magnus effect? Why ??? It is awesome!

Also I know that the algorithms are often tested against wind tunnel experiments, but wouldn't the implementation also be worth the test? There are many demons I can think of between the numerical algorithm and their implementation.

Great job! I loathed working in the field of CFD due to its penchant for old Fortran and non engineers doing IT tools.

There are some real-life applications already, eg https://www.norsepower.com/passenger/

Really want to try to test that rotating cylinder case shown in the paper. Apprecitate anyone could pin point the source code to run a simple case like that.

The case from the paper is open and available here: https://github.com/ExtremeFLOW/flettner_rotor

However, it need some work to get it running with more recent versions of Neko.
