摘要：

This paper deals with the advantages given by the use of domain decomposition methods to solve non-linear problems on a sequential system by a direct method. In addition to the benefits concerning parallel computing, domain decomposition methods offer the possibility of recalculating at each iteration of the resolution of a non-linear problem only the subdomains which were modified or which have the most important remainder at the previous iteration. For non-linear problems where the non-linearity is irregularly distributed on the structure, we show on different examples that this property may result in an important reduction of the total execution time.
