Abstract : This Note deals with problems arising in the sensivity analysis for fluid-structure interaction systems. Our model consists of a fluid described by the Navier-Stokes equations interacting with a solid under large deformations. We show how to obtain the linearized problem satisfied by the derivative of the state variable with respect to a given boundary parameter. This is done by using a particular def inition of the first-order correction for the perturbed state and by considering the weak Arbitrary Eulerian Lagrangian formulation for the coupled system.
