This is the same flow, but using a shape that was optimized using the Fusion 360 add-in "Airfoil Tools" ( [ Ссылка ] ) .

Notice the significant delay of separation. The LBM method doesn't have parameters for the quality of the airfoil or the initial turbulence of the incoming flow, which were both assumed to be excellent by the particle-swarm optimizer - which calculated about 200:1 L/D for this ideal shape. An even better solution is possible if less-than-ideal nCrit factors are chosen during optimisation!
