This function corrects the aerodynamic forces from UVLM based on the airfoil polars provided by the user in the aero.h5 file
These are the steps needed to correct the forces:
+
* The force coming from UVLM is divided into induced drag (parallel to the incoming flow velocity) and lift (the remaining force).
* The angle of attack is computed based on that lift force and the angle of zero lift computed form the airfoil polar and assuming a slope of :math:`2 \pi`
* The dreag force is computed based on the angle of attack and the polars provided by the user
