Comparison with component mode synthesis
The component mode synthesis method (also known as the Craig-Bampton method) has been developed to permit the structure to be subdivided into components (substructures), with most of the analysis being done on the smaller components to develop an approximate model for the entire structure.

The substructures in Abaqus/Standard are, in fact, a particular case of the Craig-Bampton method extended to allow for large rotations and translations of the substructure (component). The component mode synthesis method is based on the assumption that the small deformations of a substructure can be modeled using a collection of modes.
