Hello Markus, 


 


The easiest way to change the angle of attack would be to infact change the directions of the velocity components. For a velocity inlet boundary condition, specify the x-component velocity as velocity*cos(angle of attack) and y-component as velocity*sin(angle of attack). That will "in effect" change the angle of attack of the airfoil without the need for geometrical/mesh level modification. 


 


Thank you,
