PGD-based local surrogate models via overlapping domain decomposition: a computational comparison

An efficient strategy to construct physics-based local surrogate models for parametric lin?ear elliptic problems is presented. The method relies on proper generalized decomposition (PGD) to reduce the dimensionality of the problem and on an overlapping domain decompo?sition (DD) strategy to decouple...
