Hi! Quick question, for point 2 I should work with a specific PR? or should I need to create a PR for fix this? I will start to work on it.

Exactly, as we discuss you should work in your own branch, open a PR and then request for a member to review it 📑

Hey guys, do you think would be nice to have this example instead of the wind turbine one ?

[jorgepz]

Yes! Would be nice to update the wind turbine example indeed. I would show only one model of deformation and would use a propper factor in the time.

Hi guys, I found Reference Wind Turbines of NREL this are open researching geometries validates by NREL so I am trying to implement all the geometry now. At the same time I am working in implement a uBEM (unstedy Blade Element Method) recommended by Martin Draper as part of MFC course. I will upload some results soon.
