Hi @MiguelBaron

Awesome work! Thanks for sharing and for providing some insightful links.
Really liked your wind tunnel animations.

Cool design!
Yes, we need smaller, more efficient vehicles.

[I’ve been exporting Rhino .step 's to FreeCad only to use their preprocessing, and Paraview for post-processing. At one time, there was Butterfly CFD for OpenFoam, but it was more difficult to use–and was more oriented toward building effects, than an enclosed test section.]
