Model order reduction is widely used in the simulation of elastic bodies. In substructured settings, model order reduction using moment matching methods has shown to be advantageous. Using these methods, the minimal order of the reduced system depends directly on the number of interactions. This motivates the use of interface reduction methods. In this contribution an approach for interface reduction using a general singular value decomposition (GSVD) is presented. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
