Abstract

In the dynamic analysis of structures condensation methods are often used to reduce the number of degrees of freedom to manageable size. Substruc- turing and choosing the master variables as the degrees of freedom on the interfaces of the substructures yields data structures which are well suited to be implemented on parallel computers. In this paper we discuss the addi- tional use of interior masters and modal masters in substructuring. The data structure is preserved such that the condensed problem can be determined substructurewise. 1 Introduction In the analysis of the dynamic response of a linear structure using finite ele- ment methods very often prohibitively many degrees of freedom are needed to model the behaviour of the system sufficiently accurate
