Abstract:
The permanent increase in available computing resources can achieve more and more ambitious numerical simulations (most of the time using the nite element method). When dealing with non-linear complex models on large 3D structures, the computational cost becomes prohibitive. In this paper, we present the recent developments linked to an innovative computing method: non-intrusive coupling. Such a method allows to efficiently take into account local modi cations on an initial existing model in a non-intrusive way: the previously computed analysis is left unchanged. Large scale linear models can thus be easily computed, then localised non-linear complex models can be used to pinpoint the analysis where required on the structure. After a presentation of the scienti c context and a description of non-intrusive coupling methods, we will present its application to crack growth simulation and parallel structure analysis.
