A method of analyzing a finite element model of an airfoil assembly. The airfoil assembly comprises a main airfoil element and a plurality of control surfaces. The method comprises: generating a loads interface model of the airfoil assembly comprising: data which defines the spatial positions of a set of nodes, and data which associates each node with either the main element or one of the control surfaces. Load data is generated which defines loads acting on the nodes of the loads interface model, and mapped onto a finite element model to produce a loaded finite element model. A stress analysis is then performed on the loaded finite element model, and the finite element model can be refined as a result of the stress analysis.
