Fluid structure interaction
 

Hi,I am currently doing research on fluid structure iteraction at transonic speed with RAE2822 aerofoil.Instead of using a rigid body or hard material for the aerofoil,it was allowed the aerofoil to deform, and with constraints at the leading edge in all DOF,quite similar to rotor blade. Does it need to have a couple convergence between the aerodynamics and the structure at particular angle of attack before I increase the incident to maintain the lift at constant speed?
