Our work concerns the implementation of a method for convenient multiscale numerical simulation of complex structures, applied to the modeling of aircraft components (including rotating parts made of jet engine from laminate composite structures). These developments are based on the Arlequin method which allows to enrich numerical modeling, using patches around areas of interest where complex phenomena occur. This method is implemented in a general framework in order to link made of incompatible meshes in the Z-set{Zébulon finite element code, using an optimal formulation of the coupling operators. The accuracy and robustness of this approach were evaluated on various numerical problems. To increase the performance of the Arlequin method, a specific solver based on domain decomposition techniques has been developed to take advantage of computing capabilities offered by parallel machine architectures. Its performance has been evaluated on different numerical assessments from academic to industrial tests. Finally, these developments have been applied to the simulation of problems made of laminate composite structures.
