              <p>Les méthodes FFT, très performantes pour la simulation numérique du comportement de matériaux hétérogènes, sont utilisées sous l’hypothèse de conditions aux limites périodiques. On se propose ici d’étendre ces méthodes à des chargements variés combinant sur chacune des faces des conditions de type Neumann, Dirichlet ou périodiques, uniformes ou non. On s’intéresse dans un premier temps aux problèmes de conduction, première étape vers les problèmes mécaniques. De plus amples détails seront disponibles prochainement dans un article récemment accepté [1].</p>
