This submission contains an implementation of the modal substructuring approach described in Chapter 9 of Ginsberg, вЂњMechanical and Structural Vibrations,вЂќ Wiley, 2001. The well known Craig-Bampton component mode synthesis method is a special case of the approach implemented here. The routine вЂ?ritzscombвЂ™ can be used to predict the mode shapes, natural frequencies and damping ratios of an assembly of substructures from the modes of the subcomponents and the constraints that are to be enforced. For simpler problems where one wishes to add or remove rigid springs or masses from a structure, the routine вЂ?ritzsmodвЂ™ can be used.
The methods implemented here were recently used in the following publication, where the вЂњmodal constraintвЂќ method, implemented in вЂ?mkmodalconstrвЂ™ was described in detail.
