| 1. A method for performing dynamic analysis of a physical system, the method comprising
obtaining a physical system or a design of a physical system;
translating said physical system or design of a physical system into a mathematical model by causing a computer system programmed
to carry out such translation to perform steps of:
sub-structuring said system into a plurality of sub-structures;
modelling said sub-structures into sub-structure models and modelling interfaces between said sub-structure models;
combining said sub-structure models at the interfaces into a combined system;
solving the combined system,
wherein said modelling comprises performing a generalized eigenvector analysis on a discretised model of at least a subassembly
including at least two said sub-structures;
said computer system presenting results of the translation to a user, to enable such user to determine dynamic properties
of said physical system or said design of a physical system.
