Automatic, black-box model order reduction using radial basis functions

Finite elements methods have long made use of model order reduction (MOR), particularly in the context of fast frequency sweeps. In this paper, we discuss a black-box MOR technique, applicable to a many solution methods and not restricted only to spectral responses. We also discuss automated methods for generating a reduced order model that meets a given error tolerance. Numerical examples demonstrate the effectiveness and wide applicability of the method.
