I DO! PICK ME PICK ME!!! First, be aware of FluidX3d [0] [1] - which is awesome for CFD simulations, OSS, etc... Here is the premise of the CFD question: It has long been known that Eddies [2] were studied by da vinci - and he was the first to propose the eddy pump... and how eddies work in hydrodynamics - and aerodynamics. The barnacles on the leading edge of a Wales fin is also thought to cause beneficial eddies in the fin's ability to cut through water more efficiently with less drag. Dimples on a golf ball affect the air-flow in tiny micro eddies, but at extraordinary speeds - where (I surmise) a certain amount of 'cavitation' may occur with a very thin film around the ball - kind of like water-tension, but with tiny eddies [4] SO: Create a Helicopter blade with leading-edge 'Barnacles' similar to the shapes of the Acorn barnacles on

wale fins, which will create eddies as the air passes/affect the flow of the air over the foil. Add dimples of varying shape profiles (such as convex round dimples to hexagonally based dimples (much easier in aircraft which are already based on titanium honey-comb-sandwhich materil) But make the dimples morphic - being able to electrostaticly "activate" the dimples (meaning they are either on or off for the simulation) The goal is to determine the characteristic of having dimples and/or barnacles have a net positive impact on the flow and conditions of air over a foil in the helicoptor blade - or the fixed wing of larger craft - or the entire fuselage dimpled like a golf-ball affecting fuel efficiency or other factors of lift or flight that could be visualized easily using something like [0] [0.0] https://github.com/ProjectPhysX/FluidX3D [0.1] https://www.youtube.com/watch?v=mhacLfz92h0 <--- This is a fantastic video tutorial on installing FluidX3D [1] https://www.reddit.com/r/CFD/comments/10ghc2d/fluidx3d_blows...
