           | 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.

           | Really want to try to test that rotating cylinder case shown
           | in the paper. Apprecitate anyone could pin point the source

             | The case from the paper is open and available here:

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