Abstract:
Solutions of partial differential equations could exhibit a multi-scale behavior. Standard discretization techniques are constraint to mesh up to the finest scale in order to predict accurately the response of the system. The proposed methodology projects the solution of the PDE into a set of parent unidimensional spaces which are solved following the standard PGD rationale. The proposed methodology can be seen as an alternative to circumvent prohibitive meshes arising from the necessity of capturing fine scale features.
