This paper revisits a new model reduction methodology based on the use of separated representations, the so called Proper Generalized Decomposition—PGD. Space and time separated representations generalize Proper Orthogonal Decompositions—POD—avoiding any a priori knowledge on the solution in contrast to the vast majority of POD based model reduction technologies as well as reduced bases approaches. Moreover, PGD allows to treat efficiently models defined in degenerated domains as well as the… 

Local proper generalized decomposition

An extension of local models in a PGD—and thus, a priori—context is presented and no gluing or special technique is needed to deal with the resulting set of local reduced‐order models, in contrast to most proper orthogonal decomposition local approximations.

The proper generalized decomposition is a well‐established reduced order method, used to efficiently obtain approximate solutions of multi‐dimensional problems in a procedure that controls the

Nonincremental proper generalized decomposition solution of parametric uncoupled models defined in evolving domains

The case of decoupled kinematics, that is, models whose solution does not affect the domain in which they are defined, is addressed, solved by using natural neighbor Galerkin methods within a nonincremental space–time framework that can be generalized for addressing parametric models.



Recent Advances and New Challenges in the Use of the Proper Generalized Decomposition for Solving Multidimensional Models

This paper revisits a powerful discretization technique, the Proper Generalized Decomposition—PGD, illustrating its ability for solving highly multidimensional models. This technique operates by

Proper generalized decomposition of multiscale models

A space-time separated representation is proposed for the global model (this is simply the radial approximation proposed by Pierre Ladeveze in the LATIN framework) and the treatment of the local problem is globalized and then fully globalized by introducing a new coordinate related to the different species involved in the kinetic model.
