Keywords: Lagrange Multipliers, Aeroelasticity, Coupled Problems, Variational Methods

Several aspects of coupling techniques are considered to handle Computational Aeroelasticity. One main problem is to advance the overall solution in time and two possibilities are discussed - simply staggered and iterative staggered schemes. A hybrid formulation can further be integrated to consider different discretizations of the interface meshes.
