It is much better to apply a pressure to a wing and allow the displacement to be computed.
Break the wing up into surface patches to allow different pressure to be applied to leading edge patches than trailing edge patches. Make patch segments along the length of the wing.
Say you have 8 patches, 4 along the leading edge and 4 along the trailing edge. Output the deformation of 10 points along the leading and trailing edges and compute the error at each point between the actual deformation and the target deformation. Iterate the 8 values of pressure until the error is reduced to an acceptable value.
